Bug fix: dark mode colors

I've released a bug fix for some of the dark mode color problems

Someone reported an issue on Github with the colors in dark mode - the pop-ups and a few sections of the site weren’t changing to dark colors correctly, so the text wasn’t readable.

That’s fixed now, and you should be seeing it on your end already.

If you come across any other bugs or broken stuff, please let me know! I’ll do my best to get them fixed as soon as I have time to spend on it.
