Mineral Deck
Five blue hour stops with room to breathe — #006072 grounds, #008ca5 and #37a8c2 do the talking, #5fb6cc softens, #7cd3e9 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.
