Umber Outpost
Five stops tuned to sit together without fighting — #7f001b ink anchors the set, #fc8485 opens it up, and #b62e3b, #d64d54, #dc686a cross the middle in a complementary arrangement. Umber Outpost suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
