Opera palette
Crackling Delta
Five opera stops with room to breathe — #004f7e grounds, #0078bc and #3294da do the talking, #57a3df softens, #73c0fe lifts. The analogous 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.
