Brumal Fjord
Five stops tuned to sit together without fighting — #7c1c00 ink anchors the set, #fd8c6e opens it up, and #b83814, #d75635, #de6f53 cross the middle in a analogous arrangement. Brumal Fjord suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA as a text pair.
