Iris Depot
Five stops tuned to sit together without fighting — #7d2c24 ink anchors the set, #eda196 opens it up, and #a8574c, #c67266, #cf867b cross the middle in a triadic arrangement. Iris Depot suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
