Folder Images "Fill color" does not switch with light/dark mode

the new "Folder Images" section is nice,
however it appears the "Fill color" can not be set to corresponding dark or light mode.

the image overlay works well with opacity,
but if you set the fill color while in dark mode it looks horrible when dopus switches to light mode etc...
therefore making the fill color option pretty useless, unless you never switch modes

Colors outside of the main Colors and Fonts Preferences don't have separate light/dark options. We might add that in the future, if we can come up with a way that doesn't make things too complex to configure.

(Equally, someone might want different per-folder images for the two modes. While some people won't want that.)

ok thanks.
would definitely like to see that in the future
