Monochrome palette
Coral Harbor
Five stops tuned to sit together without fighting — #00747e ink anchors the set, #87eaf5 opens it up, and #00a2af, #3dbfcc, #69ccd7 cross the middle in a complementary arrangement. Coral Harbor suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
