Pink Square
Five stops tuned to sit together without fighting — #b2165c ink anchors the set, #ffc1d1 opens it up, and #e05285, #ff71a0, #ff90b2 cross the middle in a split-complementary arrangement. Pink Square suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
