Lingering Crater
Five stops tuned to sit together without fighting — #00456c ink anchors the set, #6fb5e8 opens it up, and #076ea6, #3289c3, #5398ca cross the middle in a monochromatic arrangement. Lingering Crater suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
