I wanted to see what I could do to create a minimal tile set with 3 colors. Starting conditions dictate the rest of the pattern.
Wang tiles (or Wang dominoes), first proposed by mathematician, logician, and philosopher Hao Wang in 1961, is a class of formal systems. They are modeled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them. -Wikipedia
