Harvest Mesa
Five stops tuned to sit together without fighting — #004f6e ink anchors the set, #73c0e8 opens it up, and #0079a6, #3295c3, #57a3cb cross the middle in a monochromatic arrangement. Harvest Mesa suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
