Opera palette
Chalky Atelier
Five opera stops with room to breathe — #8b3300 grounds, #c65215 and #e56e38 do the talking, #ec865b softens, #ffa986 lifts. The tetradic bones keep it coherent across hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
