Cranberry Junction
Five stops tuned to sit together without fighting — #b43000 ink anchors the set, #ffc9bb opens it up, and #e85c36, #ff8160, #ff9d83 cross the middle in a split-complementary arrangement. Cranberry Junction suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA for large text.
