Copper Bookshop
Five stops tuned to sit together without fighting — #8a321a ink anchors the set, #fbaa93 opens it up, and #b65e46, #d47960, #dd8e78 cross the middle in a monochromatic arrangement. Copper Bookshop suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA for large text.
