Harvest Foundry
Five stops tuned to sit together without fighting — #7e3245 ink anchors the set, #eea6b3 opens it up, and #a95c6c, #c77786, #d08a97 cross the middle in a analogous arrangement. Harvest Foundry suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
