63/100 tiny painting challenge for 2026 (Patreon)

Popsicle for #63! The ultimate variegated wash: rainbow! The key with this effect is to only use cool primary colors to mix all the rainbow colors. Using warm and cool colors together will make a muddy rainbow. Let everything dry between layers once you have the wash down so you can add sharp details and shadows. I can't wait to see how you do with this one! Please let me know if you have any questions.

Paper: arches 140 lb cotton 9X12" paper that I've cut into 3X3" pieces, giving me 12 pieces per page.

Paint: For this project I am using a split primary palette- cad yellow deep, lemon yellow, cad red, perm. rose, ultramarine blue, cerulean, indigo and sap green. The colors I'm using today are - lemon yellow, perm rose, and cerulean.

Brushes: round 4 & 10 - Princeton
