Pattern Production

I decided to create a tile-like pattern once I’d realized that I could overlap colors to create new ones by using the fourth parameter of fill(), which modifies opacity/transparency. The overall aesthetic reminds me of the tile work one would expect to find at the bottom of a fountain. I think this project gave me a firm understanding of the visual capabilities of nested for-loops (although I shudder to think what a nested-nested-nested for-loop would look like).
