I don't want to use a high contrast theme because that is too uniform and removes transparency; I was able to use a program called SMACC to modify most of the colors that the overall color settings in Windows 10 doesn't affect, as indicated here. These seem to be the same settings accessible in only numerical terms at Registry Editor entry HKEY_CURRENT_USER\Control Panel\Desktop\Colors.
But there is a part of the UI that cannot be edited at that level, this white-gray part as seen in Notepad:
I know there is a way to do that, high contrast themes can do it, for example this one.
But can such changes be enabled without the high contrast mode that disables transparency etc?
I have already tried SMACC and Classic Color Panel (now non-free), but they do nothing more than modify Registry Editor entry HKEY_CURRENT_USER\Control Panel\Desktop\Colors. There is also WinPalleter that looks more complicated, but I think cannot change the specific aspect I address here.
