Monochrome palette
Sultry Ridge
Five stops tuned to sit together without fighting — #005e81 ink anchors the set, #8bcff4 opens it up, and #3288b0, #51a4cd, #6fb2d6 cross the middle in a analogous arrangement. Sultry Ridge suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
