Luminous Crater
Five stops tuned to sit together without fighting — #b31f32 ink anchors the set, #ffc2c0 opens it up, and #e1575c, #ff7678, #ff9492 cross the middle in a tetradic arrangement. Luminous Crater suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
