I've been starting to learn about art theory and colouring via Kit and Clowder.
Have you heard of them? They offer colouring classes that cater for beginners to advanced colourists.

This is the October monthly colouring class for makers. Apart from the feeling of achievement you get when you colour something up that used to be just black lines, colouring can be very therapeutic!
