Opera palette
Mineral Cellar
Five opera stops with room to breathe — #731400 grounds, #b32906 and #d3492c do the talking, #d9654c softens, #f98167 lifts. The monochromatic 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.
