Butter Reef
Five stops tuned to sit together without fighting — #004d34 ink anchors the set, #71bf9b opens it up, and #007a54, #31956e, #54a27f cross the middle in a analogous arrangement. Butter Reef suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
