So I looked for a simple tutorial about how to make my own watercolor mixing chart. But the more I searched, the more confused I got !

There are loads of different types of color charts.

And some of them are not very clearly explained.

On top of that, different artists seem to have different ways of making them… I ended up looking at a lot of charts !

But it doesn't have to be that complicated. Making watercolor charts is a lot of fun and it's a very instructive exercise.

I'm going to explain the different types of watercolor charts you will commonly find and how to make a perfect watercolor chart that will serve as a reference for all your future projects.

In this article I’ll be showing you one of the most common types of watercolor chart - what is referred to as the watercolor mixing chart ”. But I’ll be covering each different type of chart in separate articles. I recommend you check out the list of each type below to get a full understanding of watercolor charts - then you can shamelessly flaunt your beautiful color charts to everyone you know !

The different types of watercolor mixing chart

  • The color wheel - This is a fundamental chart for understanding primary color mixing.
  • The mixing chart - Read this article to find out more !
  • The glazing chart - This chart shows you how your paints work together when glazing.
  • The dual color mixing chart - These charts mix only two colors but in different paint ratios.
  • The value chart - These help you to learn the proportion of water needed to mix colors of different values, from light to dark tones.
  • The palette chart - A useful chart to keep in your palette as a visual guide to the real color appearance of your paints.
  • Watercolor swatches - these “charts” are for testing single paints and provide a reference which describe the characteristics of your individual paints.

What’s the purpose of a watercolor chart ?

Have you ever been puzzled about what colors to mix in a particular situation ?

Watercolor charts are all about mastering mixing. These simple charts help you learn how to mix your collection of paints and remember which ones you need to reproduce a particular hue.

I’m always surprised by the huge variety of colors that can be created from just a few tubes of paint. If you do this exercise it will help you understand how your own paints work together. You’re going to do a lot of mixing ! But that’s the whole idea…

You may be astonished by the colors your paints can produce !

How does a watercolor color chart work ?

A watercolor chart is a grid of colored squares using all or some of the paints in your palette. The grid is labeled on the top and side axis with the names of all your paints. Each square in the chart is at the intersection of a row and a column of the chart.

You fill in each of the colored squares on your grid by mixing the color on the side axis with the color on the top axis.

For example in the diagram Row 4 + Column F = 4F ​

The completed grid gives you an overview of the mixing range of your palette colors.

6 good reasons to make a watercolor mixing chart  

  • 1
    ​I always recommend using single pigment and transparent watercolor paints. Why ? Because if you mix too many pigments it often ends up as a muddy dull color. I’m sure, like me, you prefer bright vivid colors in your paintings. Mixing single pigments is less inclined to produce flat colors. A color chart will help you identify which single pigments produce a desired color mix, and you may find some 2 or 3 pigment paints which mix badly !

    ​Knowing how to mix blacks or grays with just two colors is extremely useful, (if you have a tube of black paint you’ll probably find don’t need it). A mixing chart will help you find which two colors mix beautifully to produce interesting grays and blacks.
  • 3
    ​Sometimes you also need to reduce the intensity of a color (paint that comes directly from the tube is at its brightest most intense hue). A lot of artists will be tempted to do this by adding black, but black will deaden your colors ! It’s much better to add a complementary hue, and your color chart will help you identify the right combination.

    Mixing greens can also be quite tricky. When we go to mix paints we find it difficult to pick the right combination to get the right shade of green. A color chart goes a long way to helping with this.
  • 5
    Pinks and skin tones can be particularly frustrating to mix. A lot of beginners will mix red with white paint. The results are similar to when you try to mix a color by adding black. Your colors will look flat and uninspiring. There are several combinations that will produce great flesh tones and your mixing chart will help you discover them.

    ​Do you really need all those tubes of brown, indigo and violet ? Convenience mixtures like these are useful if you need a very specific color all the time, but you can probably mix these colors with your existing palette of paints. Making your own color chart could save you money because you’ll know how to mix a color using two other paints. You may find that you end up using less colors.This is especially useful to know if you intend to paint while traveling, so you can make your own small travel palette.

​Even if you have a limited palette you’ll probably find some pleasantly surprising mixing results along the way. 

And in the end a good chart will make your life easier.

I’ve used 8 colors for this example mixing chart but you can use more or less. You can use any combination of colors you want to test. Quite often if you get a new palette set from a particular manufacturer, it’s a good way to test the mixing capabilities of your new paints.

So sit back, grab a coffee and have some fun !

I like to do things the easy way.

But at the same time I kind of like things to look neat !

Most artists will ask you to grab a ruler and measure a grid of squares. If you don’t want to go to all the trouble of measuring, I have a quick and easy solution for you. Download my printable watercolor chart template

Try sticking a sheet of watercolor paper in your printer and print out the template, (thin 190 gsm paper may work best). Or you can trace the template onto watercolor paper using a lightbox or against a window, (this is what I do).

Psst… Sometimes you don’t even need to draw a neat grid ! Just sketch a few lines in your sketchbook.

My own color chart was designed for 8 colors, which are taken from my recommended limited color palette. ​

​How to make a watercolor mixing chart

1. Prepare your materials

Obviously you’re going to need paper, and a brush. I used a round brush size 8, and a sheet of hot pressed 300 gsm watercolor paper for my color chart. You will also need:

  • ​All your paints
  • ​A pencil
  • ​2 jars of water
  • ​Paper towels or a rag.

2. Setting up the color chart.

First of all count your paints.

The number of paints = the number of squares along each side of the chart.

For example, this chart includes 8 colors giving a total of 64 squares. I like to leave a gap between the squares, otherwise you have to wait for the paint to dry before painting adjacent boxes.

You can either sketch or draw your chart with a pencil and ruler or download my ready to go template.

3. Plan the order of your colors

I like to arrange my colors according to the hues of the color spectrum. I find it produces the most harmonious results. The order goes something like this:

Reds / oranges / yellows / greens / blues / violets / dark colors

Dark colors include paints such as Burnt Umber or Paynes Gray. Any earth colors like Raw Sienna or Yellow Ochre and pinks like Quinacridone Rose are located between the reds and yellows.

I used the following Daniel Smith paints for this chart:

Quinacridone Rose / Pyrrol Scarlet / Raw Sienna / New Gamboge / Lemon Yellow Phthalo Green (BS) / ​Phthalo Blue (GS) / French Ultramarine

4. Label your chart

Write the names of all your paints along the axis at the top and sides of the grid. Label them in the same order for each axis:

Left to right for the top axis - top to bottom for the side axis.

label the color chart

Note that the “name” of a paint is only a marketing name used by the paint brand. For this reason I like to include the specific pigments used in each paint for a better understanding of my palette.

If you’re testing one specific brand of paint you can make a note in the top left corner like I did. I’m using a waterproof pen to avoid bleeding or smudging the text.

5. Color the labels

Start by filling the labeled top and side rows with a dot of unmixed paint. This gives you a visual reference of the color appearance of your unmixed paints. It also helps associate the name of each paint with it’s color appearance.

6. The diagonal

The next step is to paint the base colors along the diagonal (this means the unmixed colors from your palette)

Follow the color from the X axis down to where it intersects with the same color across from the Y axis. For example, this is the square where Quinacridone Rose meets Quinacridone Rose or New Gamboge meets New Gamboge, etc.

Now if you look closely at your labels, you’ll realize that each “two color mix” is represented twice on the chart.

Quinacridone Rose + New Gamboge

is the same thing as

New Gamboge + Quinacridone Rose

This is why artists traditionally paint the two halves of the diagonal with a different strength of paint. I’ve put a full strength mix in the bottom left diagonal, and a watered down neutral mix in the top right diagonal.

diagonal halves of the chart

This gives you a visual reference of how the paints appear at different values.

7. Which color mix in each square ?

Now it’s time to start filling in the squares. Each square represents the mixture of two colors. Each mixture should be an equal ratio of two paints (a 50/50 % ratio).

Locate the paint your using on the X axis at the top. Then run your finger down until it intersects with the paint your using on the Y axis. These are the two paints to mix for that square.

Mix your first two paints starting in the top left corner of the chart. The most logical way I have found to proceed, is to paint the fully saturated mixture first, then add some water and paint the lighter value on the opposite side of the diagonal.

Proceed row by row and column by column. For example I chose to work on the Quinacridone Rose row first. I mixed all of the two color combinations until I reached the end of the row. At the same time, I watered down each mixture and painted the corresponding column, until I reached the bottom of the that column. Then I moved on to the next row labelled Pyrrol Scarlet. I’m right-handed, so I find this method best to avoid smudging the painted boxes.

Now keep going !

Relax and have fun. Enjoy the beautiful colors you’re creating. This is a great exercise to build your color mixing confidence.
