Blue Hour palette
Emerald Canyon
Five stops tuned to sit together without fighting — #004472 ink anchors the set, #6db3f1 opens it up, and #006cb0, #2f87ce, #5197d3 cross the middle in a complementary arrangement. Emerald Canyon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
