Font colour on Footnote

I am using the footnote widgets to display various bits of information.  I want the text to be white on a black background which is the default setting.  However, the text is actually displayed in grey.   If I put a link onto the text, then it is displayed in white - to show that there is a link.  When you hover over the link then the text turns grey. https://g51.628.myftpupload.com/events/ How can I change the system so that text is pure white and any links are shown in gray - i.e. the opposite of what it is now? Thanks
