Colour coded tracks within folders

I like to colour code my tracks, one colour for VST instruments, another for audio, etc. I also like to split my track types into folders, but when I do this, the tracks loose their colour and adopt the folder colour so they effectively all become the same colour which defeats the object of colour coding them in the first place. How do I maintain my track type colours when inside folders ?


Could you try in the Cubase Safe Start Mode [Disable preferences], please?

In my opinion, this must be something in the Preferences. But I can’t find it right now, sorry.
