Blue Hour palette
Mineral Grove
Five stops tuned to sit together without fighting — #2d63a1 ink anchors the set, #b3d5ff opens it up, and #598dcb, #74a9e9, #8cb9f0 cross the middle in a complementary arrangement. Mineral Grove suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
