Likely because it was considered to have better readability and being easier on the eyes. I don’t object. But opinions may differ, as always with this kind of things. If the name field had the subdued color and not the bright one, it could be both colored and being easy on the eyes.
It could be customized (no color/subtle color/bright color), and also some other things. I have a feature request for an optional preference for a middle way: only the fader sections to be colored (not the rack zone). I also mention the name field as a subject for preference, and some other details.
