It would be nice to automatically verify if the YCbCr Matrix of the subtitle match the video.
I did it with ffprobe, but it is surely possible with mkvtoolnix with the output of mkvmerge FILE.mkv -J. It MAY be wrong in many way since I don't know much about video color.

For more information about the YCbCr Matrix, see: https://github.com/libass/libass/wiki/ASS-File-Format-Guide#ycbcr-matrix

If I add this, it would be part of the vs-muxtools side of things. I do not feel like implementing heuristics for everything if stuff isn't tagged. There are only so many workarounds I'm willing to make to avoid vapoursynth.
