Poppy Heath
Five stops tuned to sit together without fighting — #a12f3c ink anchors the set, #ffb9ba opens it up, and #ce5e65, #ed7a7f, #f59194 cross the middle in a triadic arrangement. Poppy Heath suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
