Oil Paint Mixing Guide – History of the Color Wheel

Color and its relation to light is very similar to that of music to sound. Where color has its hues, tints, and shades, music has its many notes that create the different chords. And so it was in Sir Isaac Newton’s estimation, in his color wheel, he had a musical note that lined up with each hue. By conducting several experiments in order to better understand the relationship between colors, he succeeded when he made a hole in the shutter of a dark room and waited until a ray of sunlight shone through, he then stuck a prism into the hole, what he saw was that when the white light that reflected off the prisms, it shattered into a spectrum of colors on the white wall – into the rainbow that we know now. In Newton’s own words, “A colored image of the sun.” His was one of the earliest color wheel illustrations that is quite similar to what we are most familiar with these days.

Sir Isaac Newton’s asymmetrical color wheel with the corresponding musical intervals from Opticks: or, A Treatise of the Reflexions, Refractions, Inflexions and Colors of Light.

Since the mystery of color has long been in the minds of scientists, philosophers, artists, poets, people from all walks of life really – many others would soon follow with their own theories on oil painting color mixing, color mixing, and their own color wheels. Johann Wolfgang von Goethe for example did not agree with Newton’s theory that darkness was the absence of light, for him darkness was an essential element in color production, though his findings on his investigation into color was similar to that of Newton’s. Perhaps because of his background in literature and the arts, Goethe went into great detail about the psychological effects of color and how it may affect our emotions and behavioral traits.

Wolfgang von Goethe’s color wheel from Theory of Colors.

For the purposes of our oil color mixing, Swiss painter and teacher Johannes Itten’s color theory and color wheel is a great reference. This should help you when learning how to mix oil paint. In his wheel, 12 colors are present and have been placed in their respective areas to simplify the instruction of the primary, secondary, and tertiary colors. And he also discussed what he considers to be the four characteristics of color: its hue, intensity, value, and temperature. Just like Goethe, he studied how the different colors affect the viewer, and how each one’s perception of color may differ.

How to Mix Oil Paints Color

Primary Colors

Primary Colors cannot be created by mixing other colors. The three primary colors are, red, yellow, and blue and are the source of the secondary and tertiary colors. They are equally distanced from each other on the color wheel, separated by three color spaces between them.

The Primary Colors: blue, red, and yellow.

Secondary Colors

Secondary Colors are the colors created by mixing two primary colors together. The three secondary colors are green, orange, and violet. They are similarly equidistant on the color wheel.

The Secondary Colors: green, violet, and orange.

Tertiary Colors

Tertiary Colors are made by mixing a primary and a secondary color together. The six tertiary colors are: yellow-green, yellow-orange, red-orange, red-violet, blue-violet, and blue green.

The Tertiary Colours: yellow-green, blue-green, blue-violet, red-violet, red-orange, and yellow-orange.
I mixed a variety of yellows and blues from our ZenART Infinity Series Oil Palettes to create a foliage of greens using oil color. As you can see, it is very important to explore the different colors you can achieve by mixing certain colors together when delving into the world of color mixing.

The Four Characteristics of Color 

Hue is the spectral color or a source color, it is one of the 12 base colors that you can see in the color wheel above.

Value is the lightness or darkness of a color that can be obtained by adding pure black, pure white, or gray to it. A color is made darker by adding black, and is referred to as a “shade.” It is made lighter by adding white, referred to as a “tint.” And gray can be used to darken or lighten it, and is referred to as “tone.”

Value scale of a single color (blue), going from dark blue to the lightest tint of blue through the careful addition of white, each succeeding box containing more than the last.

Intensity is the brightness or dullness of a color, also referred to as saturation and chroma. The purer your hue is, the more intense it will be. The intensity can be reduced by adding other colors to the pure color.

There are several ways that a color’s intensity can be neutralized or decreased, and that is by mixing them with other colors such as earth tones, or as shown above – mixing with the primary hues with white, gray, and black. 
A chroma scale example, where two complementary colors are found on opposite ends of the scale, to eventually merge at the middle. The hues start out as bright, intense colors that gradually grow duller as they reach the center – which is the optimum neutral color.
Here, I placed warm and cool oil colors on opposite ends of each strip and blended them slowly towards the middle to reach a neutral “greyed” color using our ZenART Infinity Series Oil Palettes for color mixing.

Temperature is the warmth or coolness of a color. It’s important to know that green, blue, and violet have chromatic properties that make them appear cool. They can be effective in creating a quiet and calm mood that recedes into the background. While warm colors like red, orange and yellow tend to advance to the foreground. This is because warm colors have longer wavelengths than cool colors, so your eyes see them quicker than the cooler ones. If you choose a subject that is predominantly cool, then it’s good to use warm colors to serve as a contrast and a way to balance the composition, thus creating a visual effect that will grab the viewer’s attention instead of confusion as to where and what to focus on.

This is an oil on canvas painting of mine where I used warm colors for the flowers and cool colors for the leaves and the background. By creating a balance in the color temperature, it allows the viewer’s eye to focus where it should and not be overwhelmed. It is a great tool to use for creating emphasis in your composition. Oil colors used are from our ZenART Infinity Series Oil Palettes.

The use of colors is one of the fundamental elements of art-making. Just like with any skill you wish to hone, a thorough understanding of how you can use it effectively and to your advantage is a must. Too often, many of us dismiss the thought of using color wheels for color mixing and miss out on the many great advantages it can give us. Maybe you might find them too theoretical and boring, but once you give it a chance, you’ll see that they are very useful tools to use when planning out your painting’s palette. You’ll be surprised at how much easier the process becomes with the aid of the color wheel!

Of course, it seems easier to just buy the exact color selections that you want to use, rather than learning how to mix different colors yourself. However, knowing how to create your own hues is an important skill that every artist should strive to learn. Many of the celebrated masters worked with limited color palettes and yet were able to create a seemingly infinite number of colors from those. Another danger of using premixed ones is that unless you check each tube for the specific pigments used, you might unintentionally end up with mixtures that would clash with the other colors in your painting or they’d just turn out muddy. Great freedom awaits you when you can skillfully mix all the colors that your painting needs instead of merely relying on premixed colors.

Now, it’s time for you to create your very own color wheel by learning how to mix oil paints yourself. There’s no better way to start learning the wonders of color mixing! Remember, there are many versions and variations of each primary color. Some are darker, while others are lighter. Feel free to choose the version you like best, just keep in mind that your basic mixes will vary depending on the foundation colors that you choose.

Oil Paint Mixing – Color Wheel 

This is an excellent way to understand the 12 basic colors and have a better grasp of the process on how they are created. Make your own color wheel by following the steps below:

Step 1: Draw a large circle on a piece of illustration board or foam core. Try to make it as perfect as possible so you won’t have a hard time dividing it later on.

Step 2: Divide the circle into 12 equal segments. The more equal you make them, the better your color wheel will look after. 

Here is a downloadable color wheel pdf for you to practice your color mixing on. Keep in mind that this might not be suitable for oil color use when printed on regular paper.

Step 3: First, paint the three primary colors inside the pies that are positioned at equal intervals from each – one-third placements around the wheel. There should be three blank pie shapes between each color. These are Cadmium Red, Cadmium Yellow, and Ultramarine Blue.

Step 4: Now, mix the three secondary colors – green, orange, and violet. Once they’re ready, use those colors to paint the pies that are halfway between their respective primaries. You will now see a blank pie on each side of every color.

Step 5: Fill in the remaining pies with the tertiary colors that are the mixtures of the primary and secondary on either side of it. Those are blue-violet, blue-green, yellow-green, yellow-orange, red-orange, and red-violet.

Step 6: Now, you have your very own color wheel! Enjoy using it to create your color palettes!

Mixing Oil Colors

Before embarking on your new painting journey, you should first decide on what color palette to use. This will save you a lot of time and keep you from wasting your oil paint needlessly. If you are just starting out, then try using just two to four colors, they are enough to work with and to explore color mixing. Gradually increase the number of colors as you go along and as needed, you will slowly but surely master the art of color selection and mixing before you know it.


These are two colors that are on opposite sides of each other on the color wheel. Pick a color and see which one sits directly across from it, those two are complementary colors. Color combinations using this technique will be quite intense, the striking contrast can be dynamic, bold, and even bring an element of excitement to your composition. These colors create great chromatic tension when placed next to each other.

Orange and blue as indicated above, are an example of complementary colors, they are found directly opposite each other on the color wheel. Each color on the wheel has a corresponding complementary color.
In Vincent Van Gogh’s “Sunflowers,” the orange color of the sunflowers was contrasted against a blue background. The effect is quite strong and the sunflowers seem to just pop out from the painting.

Harmonious or Analogous

They are hues which sit next to each other on the color wheel. These colors produce a calming effect, easily blend in harmony when used together in one composition, and are often found in nature. When using this technique, one color serves as the more dominant of the three, while the other two support and accentuate it. So, it is crucial to create contrast so your painting doesn’t come out as too flat, one way to do this is by exploring the varying values and intensities you can use. 

A fine example of this are the yellow, orange, and browns hues that are often found during the autumn season. The yellow-green harmonies associated with the zesty landscapes of spring make for a great analogous color scheme as well. The next time you’re out or if you’re lucky to have such views from the comforts of home, take a look around or outside and see the countless harmonious colors that abound in nature that are just ripe for your color mixing picking.

As shown here, colors that sit next to each other on the color wheel are considered to be analogous or harmonious colors.
Claude Monet’s “Water Lilies and Japanese Bridge” is a fine example of an analogous or harmonious color scheme. He used mostly greens and blues for this painting and created contrast by adjusting the value and intensity levels of his colors.


They are three (tri) colors that are equally distant from each other that you will find on each tip when you draw a triangle over the color wheel. There will be three color spaces between each of the triadic color combinations that separates them. It can be challenging to use this color harmony as the colors are quite strong and can be jarring if you’re not careful, just make sure to choose one as a dominant color and use the other two as supporting ones.

The Triadic colors indicated here are red-orange, yellow-green, and blue-violet. They are equally distanced from each other by three color spaces.
Johannes Vermeer’s “Girl with a Red Hat” uses the triadic combination of red for the girl’s hat, a deeper blue for the clothing, and a subdued yellow for the majority of the background. By deepening the shades of the other two colors, red was allowed to dominate just perfectly. Color mixing here was limited to the tonal values of the three colors predominantly used.

Split Complementary

This is a color harmony that creates a color contrast but less intense or visually jolting. It is similar to the theory behind complementary colors, but in this case you have a base color and instead of using the color that is directly opposite the base color, you use the two colors found on either side of it – splitting it. So if your base color is yellow, the other two colors are red-violet and blue-violet (the two colors on either side of violet).

An example of a split complementary color harmony using yellow as the base color, with red-violet and blue-violet as the other two colors.
Henri Matisse’s “La Danse” used red-orange as the base color, with a deep green and deep blue as the two other colors. The bright red-orange of the dancing figures is balanced out by the subdued cool colors of the background.


They are colors that are rectangularly spaced apart on the color wheel, and are four (tetra) colors in total that are made up of two sets of complementary colors. This can be a challenging color scheme to manage as it can get sloppy easily, but as long as you remember to use one color as the dominant one when mixing oil paints and experiment around with the balance of warm and cool colors, then this combination gives you more room to work with.

An example of a Tetradic color harmony using red, orange, green, and blue.
Georges Seurat’s “A Sunday Afternoon on the Island of La Grande Jatte” uses the Tetradic color combination quite skillfully. He used the colors blue, green, orange, and red to create a setting that is filled with color but not visually jolting.


This color scheme also uses four colors, but unlike Tetradic, they are evenly spaced from each other with two color spaces between each other. Similarly, it’s best if you choose one as your dominant color, and carefully balance it together with the rest by paying close attention to the relationship between the warm and cool colors.

The Square color combination illustrated here are red, yellow-orange, green, and violet.


When defined, it literally means “without color.”  You solely use black, white, and shades of gray. They are considered to be lacking in hue and therefore neutral. For example, charcoal and graphite drawings are viewed as achromatic.

Achromatic Tonal Scale
Pablo Picasso’s “Guernica” is a masterpiece in itself and in the use of an Achromatic color harmony. It is a purely black, white, and gray painting depicting the horrors of war and is one of his most well-known works.


A monochromatic color harmony uses one hue only and relies on the different tints, tones, and shades of that hue. This is a great way to practice creating effective designs through the exploration of the tonal values of each color.

Monochromatic Value Scale example of one hue – red.
Claude Monet’s “Morning on the Seine, near Giverny” mainly used the color blue-green to capture the cool and misty atmosphere of the scene.

Having gone through the different color schemes you can use, it’s best to make studies and experiment before you decide on which one is best for your painting. You must keep in mind the harmony of your composition when applying  your own oil painting color mixing recipes. Many inexperienced artists will work on a small area of a painting, and move to the next area once it is finished. This jumping from one area to the next without visualizing everything as a whole creates discordance and confusion in the painting, as we have the tendency to forget the colors and style we applied in a specific area when suddenly switching to another, then another, and before you know it, things have been lost along the way.

My Tip: It is better to work on the whole painting at once. Move your eyes around the subject and the different elements, evaluate the relationships of the various colors and tones, and continue to make the necessary adjustments or changes as you go. This way, the painting will develop and evolve harmoniously at every and any stage of the process.

Creating Fabulous Colours With Oils (4) - COLOUR MIXING GUIDE

Have fun creating your own color mixtures! Remember: Experimentation is key. Don’t be afraid to add pigments and discover new oil colors on your own. Record your formulas, and keep them in a handy color journal you can refer to for future reference. 

Along your creative journey, there will be people who will try to persuade you to use certain color harmonies over the others. That’s okay, but you should listen to your soul and do what gives you pleasure and satisfaction. The color harmonious listed here are there to give you guidance and help you master your color mixing, but they are not set in stone. Start by learning them to help build your technique and confidence, before long you’ll be creating your very own color combinations.
