Opera palette
Obsidian Marsh
Five opera stops with room to breathe — #004260 grounds, #006b98 and #2f86b5 do the talking, #5094bc softens, #6cb1da lifts. The tetradic bones keep it coherent across music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA as a text pair.
