Copper Grove
Five stops tuned to sit together without fighting — #646b00 ink anchors the set, #d4de8b opens it up, and #8c962f, #a7b24e, #b7c16f cross the middle in a triadic arrangement. Copper Grove suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
