Blue Hour palette
Oyster Canyon
Five stops tuned to sit together without fighting — #9f1a00 ink anchors the set, #ffad9c opens it up, and #d14b33, #f1684f, #f7826b cross the middle in a tetradic arrangement. Oyster Canyon suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
