Blue Hour palette
Russet Canyon
Five stops tuned to sit together without fighting — #0f629c ink anchors the set, #a4d4ff opens it up, and #478cc6, #63a8e4, #7eb7eb cross the middle in a complementary arrangement. Russet Canyon suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
