Dusty Crater
Five stops tuned to sit together without fighting — #005c81 ink anchors the set, #84cdf7 opens it up, and #2686b4, #47a2d1, #68b0d9 cross the middle in a monochromatic arrangement. Dusty Crater suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
