Blue Hour palette
Autumn Junction
Five stops tuned to sit together without fighting — #004a8a ink anchors the set, #7fbbff opens it up, and #2472c2, #428ee0, #609ee5 cross the middle in a tetradic arrangement. Autumn Junction suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
