Fern Caravan
Five stops tuned to sit together without fighting — #004468 ink anchors the set, #6db3e4 opens it up, and #006da2, #2f88bf, #5197c6 cross the middle in a complementary arrangement. Fern Caravan suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
