Colour follows bus..even if going via an aux track

[grannis]

I am a big user of aux tracks, but I also love the "colour follows bus" option. Trouble is, if you set the output on a bunch of tracks to an aux, then output the aux to the bus, the colour of the tracks does not follow the bus, or even the aux track that they are being sent to. 

What would be really cool, is if the aux track followed the bus, and the tracks that are output to the aux track follow the colour of the aux track, thus inheriting the colour of the bus, if you want it to.
