   signal-ink  text that sits on signal
   accent      pills, buttons, small highlights
   accent-ink  text that sits on accent
   deep        always-dark surfaces (footer, topic header, badge art)
   deep-soft   secondary text on white badge art
   on-deep     text on deep
   pop         highlight colour that reads on deep
   link        brand colour for text on the page background
   Pick one in Ghost Admin: Settings > Design > Customize > Palette.
