Earthen Courtyard
Five stops tuned to sit together without fighting — #9f2b43 ink anchors the set, #ffb6bc opens it up, and #cc5b6b, #eb7785, #f38e99 cross the middle in a triadic arrangement. Earthen Courtyard suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
