The GI pass

Not sure how you do that in Blender but in Nuke you could just use a Keyer node attached to the GI pass to isolate the area around the object. First you grade the GI pass to make the individual areas distinct, then you use a keyer to create a mask only on the area where you want to change the color, then you use this mask to grade the original GI pass.
I'm sure there are also other methods, probably even better than this one.
You can also create different render layers for each object and then merge them together at the end, thus giving you freedom
