Sumi palette
Stormy Kiln
Five stops tuned to sit together without fighting — #9f2f0e ink anchors the set, #ffb7a4 opens it up, and #cc5e42, #eb7a5d, #f29177 cross the middle in a monochromatic arrangement. Stormy Kiln suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
