Blue Hour palette
Opal Square
Five stops tuned to sit together without fighting — #005492 ink anchors the set, #8ec6ff opens it up, and #0e7dd2, #3899f1, #5ca9f4 cross the middle in a split-complementary arrangement. Opal Square suits flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA for large text.
