Rustic Heath
Five stops tuned to sit together without fighting — #004a51 ink anchors the set, #70bac3 opens it up, and #007580, #31909b, #549ea7 cross the middle in a analogous arrangement. Rustic Heath suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
