Sunlit Alley
Five stops tuned to sit together without fighting — #005254 ink anchors the set, #74c3c5 opens it up, and #007e81, #33999c, #58a7a9 cross the middle in a tetradic arrangement. Sunlit Alley suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
