This is interesting, because I've latched onto a particular color of masking tape for labeling. It's a light green, a color shared by very few other objects in the indoor environment.

It stands out against cardboard and all the variously-colored plastic boxes I own, and it's light enough to offer great contrast with a black Sharpie on it.

So for me, that color is useful specifically because it's relatively unique.
