  /**
   NOTE for all *-text variables
   ----------------------------------------------
   The text-variables are present as triplets
   because in some places it's required to adjust
   their transparency.

   So, for general usage, use:
   color: RGB(var(--*-text));

   And for transparent usage, use:
   color: rgba(var(--*-text), .7); 

   The uppercase RGB is required because internally
   SassC wants more than one argument for rgb(),
   hence writing RGB() bypasses that check, but
   browsers interpret it correctly.
