Colour Theory Diamonds

” I found I could say things with color and shapes that I couldn’t say any other way – things I had no words for” – Georgia O’Keeffe

This is a fun project to introduce colour theory.


Supplies needed:

Water colour paper

We started by talking about diamond shapes, it helps to look at a diamond or draw one for an example. Once you have drawn a diamond big enough to fill the page, the fun part starts.

If your child has not used a ruler before, they will enjoy using one. I like using the ruler because it creates nice clean lines. I had my children start from the bottom of the diamond and make three straight lines up, as long or as short as they wanted. Then, from there I asked them to close the ends with a line and continue to create closed shaped with the ruler inside the diamond. You can make lots of angles and squares, any size works, just make sure they are having fun. It doesn’t have to be too complicated.

The one pictured below was by my three year old, he didn’t get perfect lines but he loved joining in. We are always about the process and encouragement.



It is good to remind your child that the more lines they create, the more space they have to colour in. If they have a lot of lines, in the end they may feel a little overwhelmed colouring in every shape, and then for some it’s highly enjoyable.



Once you are happy with your diamond, start with the three primary colours, yellow, red and blue. From there, you teach the secondary colours, and keep mixing as you like.
