Mineral Grove
Five stops tuned to sit together without fighting — #483c8f ink anchors the set, #b3affb opens it up, and #6e66b9, #8881d7, #9793dd cross the middle in a tetradic arrangement. Mineral Grove suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
