Perennial Clearing
Five stops tuned to sit together without fighting — #005e6a ink anchors the set, #7bd0e0 opens it up, and #008a9c, #37a6b8, #5eb4c3 cross the middle in a triadic arrangement. Perennial Clearing suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
