These cells are done with c1 being the lightest and c5 being the darkest. Glaze them all with equal amount of transparency.
I plan on doing reverse painting using a pantograph to guide my brushstrokes. I plan on painting the K-blacks first then the rest. This is a CMYK process. Glaze, make lines, do dots, like pointillism.
Paint anyway you like.
