Birch Deck
Five stops tuned to sit together without fighting — #7c1800 ink anchors the set, #f1927c opens it up, and #ac442d, #cb6048, #d27661 cross the middle in a tetradic arrangement. Birch Deck suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA as a text pair.
