Blue Hour palette
Tawny Inn
Five stops tuned to sit together without fighting — #004069 ink anchors the set, #6baee6 opens it up, and #0068a5, #2e83c2, #4f92c8 cross the middle in a tetradic arrangement. Tawny Inn suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
