Blue Hour palette
Nightfall Library
Five stops tuned to sit together without fighting — #0061ab ink anchors the set, #acd4ff opens it up, and #008af0, #51a8ff, #74b8ff cross the middle in a analogous arrangement. Nightfall Library suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA for large text.
