I wanted an excuse to play with my new set of Faber-Castell Polychromos colored pencils so I did a quick color wheel for a ROYGBIV study.
Cheap bullet journal stencil sets have been an invaluable tool for making color swatches. I found a set on Amazon that was perfect for color wheels and this was the result. It took about two hours and I’m happy with the result.
