Blue Hour palette
Sandy Cellar
Five stops tuned to sit together without fighting — #00475d ink anchors the set, #6fb6d4 opens it up, and #007192, #308cae, #539ab7 cross the middle in a complementary arrangement. Sandy Cellar suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA as a text pair.
