Perennial Delta
Five stops tuned to sit together without fighting — #6f2e00 ink anchors the set, #ef9769 opens it up, and #aa4a00, #c8652b, #d07b4e cross the middle in a triadic arrangement. Perennial Delta suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA as a text pair.
