Sumi palette
Stone Brook
A quiet five-stop sumi arc with a confident middle — #912c00 carries the weight and #ffa98e carries the air, with #c35530, #e2714c and #e98868 bridging in triadic formation. Built for national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
