Monochrome palette
Midnight Oasis
Five stops tuned to sit together without fighting — #004f75 ink anchors the set, #74c0f1 opens it up, and #0079af, #3295cc, #57a3d3 cross the middle in a analogous arrangement. Midnight Oasis suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
