Greige Cabin
Five stops tuned to sit together without fighting — #007185 ink anchors the set, #8ce6fc opens it up, and #1f9eb7, #47bbd4, #6ec8de cross the middle in a tetradic arrangement. Greige Cabin suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
