   /* Never use color values defined here directly in CSS. Add color variables to "Color Theme" below
 
      The reason we never use color values defined here directly in CSS is
 
       1. It makes changing themes from light / dark / user generated impossible.
       2. Gives the programmer context into the color being used.
       3. If our color system changes it's much easier to change color values in one place.
 
      Add a color value to the theme below, and then use it in your CSS.
      naming convention:
      - bg: background.
      - fg: foreground.
      - color: text-color
