Blue Hour palette
Flannel Lighthouse
Five stops tuned to sit together without fighting — #731500 ink anchors the set, #e78d79 opens it up, and #a2412c, #c05c46, #c8725e cross the middle in a tetradic arrangement. Flannel Lighthouse suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
