The "Site Primary Color" link list allows you to update your primary color site wide.  To enable this option the name of a link must have an active date range that would be mm/dd/yyyy-mm/dd/yyyy.  There must not be a space between the hyphen.

Example - If you wanted to update the primary color between May 1, 2020 until May 5, 2020 the link title would be 05/01/2020-05/05/2020.  The link description would contain a six digit hex color ex. #ff0000.
