Sumi palette
Ember Square
A quiet five-stop sumi arc with a confident middle — #7d1400 carries the weight and #f0917d carries the air, with #ab432f, #ca5f49 and #d17562 bridging in triadic formation. Built for museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
