Meadow Heath
Five stops tuned to sit together without fighting — #00486e ink anchors the set, #70b8eb opens it up, and #0071a9, #308cc6, #539bcd cross the middle in a tetradic arrangement. Meadow Heath suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
