Blue Hour palette
Mercurial Hollow
Five stops tuned to sit together without fighting — #006579 ink anchors the set, #7fd8f2 opens it up, and #0091ae, #39adcb, #61bbd4 cross the middle in a triadic arrangement. Mercurial Hollow suits music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA for large text.
