Obsidian Lighthouse
Five stops tuned to sit together without fighting — #006271 ink anchors the set, #7dd5e8 opens it up, and #008ea4, #38aac1, #60b8cb cross the middle in a tetradic arrangement. Obsidian Lighthouse suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
