Oat Lagoon
Five tropical stops with room to breathe — #006668 grounds, #009396 and #39afb2 do the talking, #61bcbe softens, #7fdadc 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.
