Spruce Mesa
Five stops tuned to sit together without fighting — #005f52 ink anchors the set, #7bd3c0 opens it up, and #008d7a, #37a995, #5eb6a4 cross the middle in a tetradic arrangement. Spruce Mesa suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
