Opera palette
Walnut Delta
Dark anchor, working middle, light release: #742000, #ad3e17, #cc5a36, #d37253, #f28d6e form a complementary opera set with somewhere to stand at every lightness. Made for bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA as a text pair.
