Perennial Bluff
Five stops tuned to sit together without fighting — #7c3457 ink anchors the set, #eca8c5 opens it up, and #a75e7f, #c4799a, #ce8ca9 cross the middle in a analogous arrangement. Perennial Bluff suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
