Nordic palette
Sage Delta
Five nordic stops with room to breathe — #006070 grounds, #008ca3 and #37a8c0 do the talking, #5fb6ca softens, #7cd3e7 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.
