Pewter Cellar
Five stops tuned to sit together without fighting — #00535c ink anchors the set, #75c5d0 opens it up, and #007f8c, #349aa8, #59a8b3 cross the middle in a tetradic arrangement. Pewter Cellar suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
