Blue Hour palette
Pale Cove
Five stops tuned to sit together without fighting — #005684 ink anchors the set, #7dc8ff opens it up, and #0080c1, #349cdf, #5babe5 cross the middle in a tetradic arrangement. Pale Cove suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
