This WetCanvas! Challenge was to use only the three primary colors. When I first saw this challenge in April, it was beyond my capabilities. I wish I could do better now, but it's not all that bad for a beginner and much better than if I had tried it in April.
It's on Montval paper, but I think a different paper would have been easier, especially for the background.
The colors used were Maimeriblu's Primary Red, Primary Yellow, and Primary Blue. 5"x7".
