Coral Boulevard
Five stops tuned to sit together without fighting — #00428f ink anchors the set, #7fb4ff opens it up, and #286bc4, #4487e2, #5f98e6 cross the middle in a tetradic arrangement. Coral Boulevard suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
