Opera palette
Blushing Fjord
Five opera stops with room to breathe — #004369 grounds, #006ba4 and #2e86c1 do the talking, #5095c8 softens, #6cb1e5 lifts. The tetradic bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
