[NSFW] Need a change color to: swpm-renewal-link

Hello everyone. I have a problem, my site has a dark background and a light font. And I came across the fact that the SimpleMembership bar, reminding that the account status has expired, has a light yellow color, and against this background, the white font completely merges and becomes unreadable. How to fix it? I need the ability to change the background color to a darker one or the font color to a darker one. But not both light ones like now.
