As an admin i would like to be able to set the accent color of the Donor Dashboard to a CSS-defined global color, e.g. "var(--color1)". Currently, this cannot be done easily (the shortcode for the donor dashboard only accepts actual HEX codes, not colors in the format "var(--color1)". This is manageable via a code snippet, but this is cumbersome. It would be handier if there was a setting for this in the GiveWP settings.
