You can't , really.
In the screencapture you have a model selected, so the channel view will show you all the channels that model has.
If you cursor down to any of the items in that model (such as beam or lid or spinner ) you will get just the channels for that item. After you do that if you hit R you can toggle between seeing just the rotation channels and seeing all of them. Likewise for the N key and translation channels. S key will toggle Scale channels.
white, red, green and blue mean W, X, Y and Z axis
white is also used for property channels that are just a numerical value like cm or %
