Sumi palette
River Marsh
A quiet five-stop sumi arc with a confident middle — #7e002f carries the weight and #fd8197 carries the air, with #b72850, #d74869 and #dd657c bridging in tetradic formation. Built for national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
