Blue Hour palette
Glassy Crater
Five stops tuned to sit together without fighting — #00455c ink anchors the set, #6db3d3 opens it up, and #006e91, #2f89ad, #5197b6 cross the middle in a tetradic arrangement. Glassy Crater suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA as a text pair.
