Color Chip Charts
So I decided to make a downloadable pdf for you! It includes brief instructions on how I filled mine in and an example. The pages that are included are Faber Castell Polychromos, Lyra Rembrandt Polycolor, Caran D'Ache Luminance, Prismacolor Premier and Derwent Colorsoft.
I won't kid you, it is a lot of work if you have complete sets.
