   Six brand colours. Vermilion is the only hot one. Warm stone,
   slate grey and foundation black are data and surface colours and
   are never used as an accent.

   Signal amber is NOT a brand colour. It survives as one reserved
   semantic token for the evidence register's Untested rows, and
   appears nowhere else on the site.
