Sumac Hollow
Five stops tuned to sit together without fighting — #841600 ink anchors the set, #ff9079 opens it up, and #be381e, #de563c, #e47159 cross the middle in a monochromatic arrangement. Sumac Hollow suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
