Mustard Reef
Five stops tuned to sit together without fighting — #5f4b00 ink anchors the set, #d1ba72 opens it up, and #8d7209, #a98d33, #b59d56 cross the middle in a tetradic arrangement. Mustard Reef suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
