I think you've missed the point of the email you replied to entirely.
Please, explain what larger problem you want to solve that you believe
requires scanning for a particular color in a window, and we can almost
certainly tell you an easier and more efficient way to solve the same

Mechanisms exist in the X protocol to get a pixmap, with which you could
scan for a color, and XCB can access those mechanisms just as Xlib can.
That doesn't make using them a good idea.
