Steely Canyon
Five stops tuned to sit together without fighting — #872900 ink anchors the set, #ff9e7e opens it up, and #c1481b, #e0653b, #e77d5a cross the middle in a complementary arrangement. Steely Canyon suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
