[Dev] Sharing currently broken for collections that have a color assigned

[John Anderson]

Alec and I have been talking about storing color information in a 
separate dictionary which is associated with the data's view, not the 
data itself. This issue comes up over and over again, so we'd like to 
solve it in a general way that we reuse throughout the UI. Perhaps the 
three of us could discuss it on Skype.
