Frost palette
Halcyon Brook
Five frost stops with room to breathe — #005c68 grounds, #008899 and #36a4b5 do the talking, #5db1c0 softens, #7acedd 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.
