Monochrome palette
Greige Grove
Five stops tuned to sit together without fighting — #00669e ink anchors the set, #a7d8ff opens it up, and #2c91d4, #4dadf2, #6fbdf8 cross the middle in a analogous arrangement. Greige Grove suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
