Citrus Foundry
Five stops tuned to sit together without fighting — #9c0404 ink anchors the set, #ffa597 opens it up, and #ca473a, #ea6455, #f07e6e cross the middle in a triadic arrangement. Citrus Foundry suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
