Tutorial using gouache paint to create a colour wheel using your 3 primary colours and white.
For this project you will need;
Watercolour or mixed media paper. ( I used a square gummed block, but you may want to use an A4 sheet/pad)
Gouache paint; Red, Yellow, Blue and white (only use these colours)
Mixed media or synthetic brushes. (I used a small round brush)
Mixing palette and water pots.
Pencil
This project can take anywhere from 30 minutes to 90 minutes, depending on the amount of detail you want to add.
First draw out your template. I used a jam jar lid. Creating one centre circle and three overlapping circles. Then in between those circles I added three more. The template is at the end of this tutorial if you want to trace it down.

On a scrap of paper test your three primary colours and make sure your paint is at the right consistency.
It needs to be a nice and strong colour with only a little water to lubricate the brush, but not too thick and dry that it sticks to the paper and drags as you pull the brush along.
Now paint your three primary colours Red, Yellow and Blue on the large inner sections.
Next I mixed some white into the primaries to create a lighter version of these colours. I painted these on the outer sections in line with the first primary colours.
