Twilit Bookshop
Five stops tuned to sit together without fighting — #006461 ink anchors the set, #7ed7d3 opens it up, and #00918d, #38ada9, #60bab6 cross the middle in a monochromatic arrangement. Twilit Bookshop suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
