Luminous Bluff
Five jewel stops with room to breathe — #004e81 grounds, #0077c0 and #3293de do the talking, #57a2e3 softens, #76bfff 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.
