Opal Cottage
Five stops tuned to sit together without fighting — #004878 ink anchors the set, #6fb8f7 opens it up, and #0070b6, #308cd4, #539bd9 cross the middle in a tetradic arrangement. Opal Cottage suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
