PLEASE NOTE I have not used this method for six years and do not recommend it anymore. It was interesting, but it's hardly intuitive.
I finally finished up the colour dynamics tutorial I had promised, now conveniently available as a Christmas present from me to y'all. Thanks again to Maddy for showing me what the hell paintbrush colour dynamics even are
, and to Wicked Sairah for commissioning me.
Enjoy, and Happy Chrismahanakwanzakuh!
