Monochrome palette
Crimson Deck
Five stops tuned to sit together without fighting — #00456f ink anchors the set, #6eb4ed opens it up, and #006dac, #2f88c9, #5298cf cross the middle in a analogous arrangement. Crimson Deck suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
