How to Mix Polymer Clay Colours

FIMO Professional clay can be used to make all kinds of unique jewellery creations. To help you craft them just as you imagined, we want to show you how you can mix virtually any colour you desire. Using the FIMO colour wheel, you can create 176 colours from just five primary colour clays. Here’s how to mix polymer clay colours so that you can create clay jewellery pieces with the same result every time.

What colours are available in the FIMO Professional clay collection?

The FIMO true colours are; yellow, magenta, green, blue and red. Each one of the true colour clays contains one pure pigment which means that your combined clays will produce brilliant and bright colours. When mixed with our black and white clays, you can get precise mixing results.

How does mixing clay colours work?

With the FIMO colour mixing system, it’s easy to produce your desired colours. The main colour circle is in the centre. These colours are used as the foundation of all colour recipes. The addition of the white and black clays then produces the shades and tints that give you a harmonious rainbow of choice. To show you how it works, we will give you a step-by-step guide using an example.

What you will need:

  • Clay Machine (You can use a pasta machine if you don’t have a clay machine)
  • 1 cutter in desired size and shape
  • Fimo Professional clay in true colours
  • Fimo Professional clay in black and white

Polymer clay colour mixing in 7 simple steps:

Step 1

Before mixing your polymer clays, identify which colour you would like to create and prepare the clays needed for the recipe. In this example, we are using light orange. The code for light orange on our colour wheel is 4W + 1YIII. This means we will need true red, true yellow and white clay.


Step 2

You must first mix the colour you’re aiming for using the main colour circle. For light orange, this is 1YIII = 4Y +1R or four parts yellow to one part red.

Step 3

Using either a clay machine or even a pasta rolling machine, roll out the clays. It’s important to remember to roll all clays on the same setting. This is to ensure they are all the exact same thickness ready for cutting your sections.

Note: If you don’t have any kind of rolling machine, simply weight out each part of the clay recipe instead to ensure accurate amounts are used before mixing clay colours.

Step 4

Using your cutter, cut out the exact number of pieces dictated by the recipe. Be sure to use the same size and shape cutter at each step.


Step 5

Once you have your first sections, mix these together ready for the next stage. Based on our example you should now have the colour classified as Yellow 3 (YIII) on the FIMO colour wheel.


Step 6

According to our recipe for light orange (4W+1YIII) we need to mix 4 sections of white (4W) with one part of our created yellow 3 (YII). So once again, using the Fimo clay machine roll out the white and yellow 3 clays on an equal setting and cut out your sections.


Step 7

You can now mix your final sections together and you have achieved your preferred colour of clay!


Now that you have learned how to mix polymer clay colours using FIMO Professional clays, you can try any colour you want. By slightly changing the recipe you can achieve finely graded colours with almost as many variants as the human eye can perceive.
