Acid palette
Indigo Moor
Five stops tuned to sit together without fighting — #007472 ink anchors the set, #87ebe7 opens it up, and #00a3a0, #3dc0bc, #69cdc9 cross the middle in a tetradic arrangement. Indigo Moor suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
