Crimson Cellar
Five stops tuned to sit together without fighting — #9e0031 ink anchors the set, #ffa6ab opens it up, and #cc4559, #ec6273, #f27c87 cross the middle in a split-complementary arrangement. Crimson Cellar suits indie game interfaces with a strong day-night rhythm. The darkest and lightest stops clear AA as a text pair.
