This is a coloured page from my book, Geometric Patterns. I coloured it in a simple black, green and white palette with Tombow brush markers on printer paper.
Geometric Patterns was my first colouring book, and has 50 original pattern designs which I find very relaxing to colour. You can see the book on Amazon here, or preview all the illustrations on this page.
