Dusky Manor
Five stops tuned to sit together without fighting — #8d0024 ink anchors the set, #ff9296 opens it up, and #c72b43, #e74c5d, #ed6a73 cross the middle in a tetradic arrangement. Dusky Manor suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
