Grape Bluff
Five stops tuned to sit together without fighting — #3649c4 ink anchors the set, #b7c9ff opens it up, and #5b77ef, #7a97ff, #8fa9ff cross the middle in a triadic arrangement. Grape Bluff suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
