Polar Alley
Five industrial stops with room to breathe — #007179 grounds, #009faa and #3cbcc7 do the talking, #67c9d2 softens, #85e7f0 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.
