Blue Hour palette
Spruce Prairie
Five stops tuned to sit together without fighting — #00539c ink anchors the set, #95c6ff opens it up, and #3a7dc8, #5699e6, #71a9eb cross the middle in a tetradic arrangement. Spruce Prairie suits music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA for large text.
