Iris Delta
Five stops tuned to sit together without fighting — #a12f25 ink anchors the set, #ffb9ae opens it up, and #ce5e51, #ed7a6b, #f49183 cross the middle in a split-complementary arrangement. Iris Delta suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
