Retro palette
Spruce Bookshop
Five stops tuned to sit together without fighting — #7c0007 ink anchors the set, #f5867a opens it up, and #b0332d, #cf5147, #d66a5f cross the middle in a tetradic arrangement. Spruce Bookshop suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
