Frosted Cellar
Five stops tuned to sit together without fighting — #4e448f ink anchors the set, #bab7fc opens it up, and #746eb9, #8e89d7, #9e9bdd cross the middle in a monochromatic arrangement. Frosted Cellar suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
