Starlit Library
Five stops tuned to sit together without fighting — #05568c ink anchors the set, #90c7f9 opens it up, and #3f7fb6, #5b9bd3, #74aadb cross the middle in a tetradic arrangement. Starlit Library suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
