Pink Crater
Five stops tuned to sit together without fighting — #006282 ink anchors the set, #7ed6fd opens it up, and #008eba, #38aad7, #61b9df cross the middle in a tetradic arrangement. Pink Crater suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
