Blue Hour palette
Midnight Harbor
Five blue hour stops with room to breathe — #00689a grounds, #3993ca and #58afe8 do the talking, #77beef softens, #a5daff 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.
