Citrus Bluff
Five stops tuned to sit together without fighting — #a5351d ink anchors the set, #ffc0b1 opens it up, and #d2644c, #f18067, #f89780 cross the middle in a tetradic arrangement. Citrus Bluff suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
