Can you set multiple tracks with same track icon at same time?

I like to color-code all my drum tracks the same, all guitar tracks, vox, etc.

It would save me "minutes per year" if I didn't have to do this track by track.  :-)

Is there any way to color a group all together? 

Ah, thanks.  I should have specified that what I wanted to do was color-code the ICONS--I use colors as my icon, rather than pictures of tiny instruments.

I'd like to be able to, for instance, take all of the drum tracks and give them a blue solid color for an icon--all at once, instead of the track by track as I am doing now.  

I haven't found a way to do that.  You can assign all of their Outputs at once to a Drum Bus, but I'm not sure that I can assign all of them to have a solid blue icon all at once.

That's definitely one of the things I tried after seeing someones mixing video. I'm convinced it can't be done in that manner, however I have found the fastest way to do it. Double click the icon, that brings up choices folder. once you go to the folder with the colors, drag the edge of the window so you see all of them at once. Then it's just a matter of double clicking and picking. EDIT: I've been messing with this and i found a little faster way. All the steps apply except the double clicking. If you just hold alt you can click the icon click the color, don't let alt go until you've picked all the colors.

There is no way to insert track icons (the same or different ones) at the same time. It needs to be done one at a time.
