Coral Caravan
Five stops tuned to sit together without fighting — #004664 ink anchors the set, #6eb5de opens it up, and #006f9c, #308ab9, #5299c1 cross the middle in a tetradic arrangement. Coral Caravan suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
