Harvest Cottage
Five stops tuned to sit together without fighting — #004a7e ink anchors the set, #7abbf7 opens it up, and #2173b5, #418fd3, #5e9ed8 cross the middle in a split-complementary arrangement. Harvest Cottage suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA as a text pair.
