Aurora palette
Nightfall Harbor
Five aurora stops with room to breathe — #006989 grounds, #1395bf and #40b1dd do the talking, #67c0e5 softens, #8cdcff 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 for large text.
