Mustard Square
Five stops tuned to sit together without fighting — #923100 ink anchors the set, #ffad90 opens it up, and #c5582e, #e4744b, #eb8b68 cross the middle in a tetradic arrangement. Mustard Square suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
