Marble Dairy
Five stops tuned to sit together without fighting — #a5333a ink anchors the set, #ffbfbd opens it up, and #d26263, #f17e7e, #f99593 cross the middle in a tetradic arrangement. Marble Dairy suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
