Midcentury palette
Marble Grove
Dark anchor, working middle, light release: #7e2300, #ba4014, #d95d35, #e07655, #ff9271 form a tetradic midcentury 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.
