Spoiler Tag Appearance; Colors Clashing With Font Color

I personally find the current color scheme, with a grey spoiler text and then the text is a slightly lighter grey over a darker grey, in light mode. It's a bit easier to read in dark mode with the text being white but I prefer to use light mode.

Is it possible to implement something so that users can individually choose the spoiler tag highlight color *and* the text color, so that everyone can choose what is most comfortable for their eyes. I don't usually need to use my computer glasses most of the time these days but I find I have to in order to read what's behind a spoiler tag on a light scheme.

Thanks!
