Nebula palette
Calico Archive
Five nebula stops with room to breathe — #00645d grounds, #009288 and #38aea3 do the talking, #61bbb1 softens, #7ed8ce lifts. The monochromatic 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.
