Indigo Bluff
Five stops tuned to sit together without fighting — #004c47 ink anchors the set, #71bdb4 opens it up, and #007870, #32938b, #54a098 cross the middle in a triadic arrangement. Indigo Bluff suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
