Lunar Fjord
Five stops tuned to sit together without fighting — #822c00 ink anchors the set, #ff9c77 opens it up, and #c14500, #e0622e, #e77b52 cross the middle in a tetradic arrangement. Lunar Fjord suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
