Mineral Shrine
Five stops tuned to sit together without fighting — #00477f ink anchors the set, #71b8ff opens it up, and #026fc0, #308bde, #539be2 cross the middle in a tetradic arrangement. Mineral Shrine suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
