Mahogany Brook
Five stops tuned to sit together without fighting — #8b3a30 ink anchors the set, #fcb0a4 opens it up, and #b66559, #d48073, #dd9488 cross the middle in a split-complementary arrangement. Mahogany Brook suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
