Leaden Oasis
Five stops tuned to sit together without fighting — #9e3e00 ink anchors the set, #ffc0a5 opens it up, and #d56227, #f47e47, #fb9668 cross the middle in a split-complementary arrangement. Leaden Oasis suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
