I like the colors; this will make it easier to find the right bit when i need it. Although I'm not a big fan of the centering feature. The chamfer on the working end of these bits is very small, which limits the size of the countersunk holes they can be used with. It doesn't take long to shift these bits around with a hand drill. Probably better in a drill press, but the one I just used on a very small screw and hinge combo was questionable.
