Monochrome palette
Sumac Heath
Five stops tuned to sit together without fighting — #006b73 ink anchors the set, #82e0e9 opens it up, and #0099a3, #3ab5bf, #65c3cb cross the middle in a triadic arrangement. Sumac Heath suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
