No. The term colorsanding is probably left over from the old days of lacquer and single stage finishes. Base clear is what is often used today, so you aren't really sanding color (at least you don't want to be, that means you went through, and have some repainting to do). Today some people sand the clear dry with a orbital palm sander and special pad as well, years ago pretty much everyone sanded wet by hand (the way I still do it). They also have water bug sanders to sand by machine wet. A shop I worked at got one and saved my arms, but my shoes ended up even wetter then normal doing it that way.
