Blue Hour palette
Gleaming Grove
Five stops tuned to sit together without fighting — #00476e ink anchors the set, #6fb7eb opens it up, and #0070a9, #308bc6, #539acd cross the middle in a triadic arrangement. Gleaming Grove suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
