Bitter Lane
Five stops tuned to sit together without fighting — #004659 ink anchors the set, #6eb5cf opens it up, and #00708d, #308ba9, #5299b3 cross the middle in a complementary arrangement. Bitter Lane suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
