Blue Hour palette
Copper Parlor
Five stops tuned to sit together without fighting — #005182 ink anchors the set, #84c1f4 opens it up, and #2f7ab2, #4c96cf, #68a5d6 cross the middle in a analogous arrangement. Copper Parlor suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
