Ochre Manor
Five sumi stops with room to breathe — #7f002a grounds, #b52f4c and #d44d65 do the talking, #db6878 softens, #fb8493 lifts. The tetradic bones keep it coherent across dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
