Pastel palette
Fern Library
Five pastel stops with room to breathe — #00504c grounds, #007c76 and #339791 do the talking, #56a49e softens, #73c1ba lifts. The complementary bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
