This is one of my favorite paintings from the series so far. The classic shape of the letters just does it for me. The name of the piece comes from the color change from yellow to pink where the letters intersect.
Want to see how it came together? Here's a few quick photos, click to enlarge:
As you can see, I didn't add the pink in the letters til the last minute. It just seemed like the yellow needed a foil.
This looks like a colorful painting, but there are also lots of biscuit-colored neutrals and warm grays, so it looks great on a neutral wall.
