Select all the tracks you want with Qlink enabled and press the colour tool (i think that's number 9?) then you can press an arrow under the color tool which will offer you colors (you can also add your owns which i did) just choose one of the color and all the selected tracks will turn this color be it a group a midi a folder or whatever including the color of the recorded parts if your track is say a mono stereo or midi.
so...
