Sunlit Ridge
Five stops tuned to sit together without fighting — #7d2216 ink anchors the set, #ed9a8b opens it up, and #a84f40, #c66a5a, #ce7f70 cross the middle in a tetradic arrangement. Sunlit Ridge suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
