Acid palette
Bitter Clearing
Five stops tuned to sit together without fighting — #004a5a ink anchors the set, #70b9cf opens it up, and #00748c, #318fa8, #549db2 cross the middle in a tetradic arrangement. Bitter Clearing suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
