Sumi palette
Cobalt Clearing
Five sumi stops with room to breathe — #7b2800 grounds, #b94100 and #d85e2c do the talking, #df764f softens, #fe926b lifts. The triadic bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
