There's another aspect of having a colored tool. It looks cute to people who don't carry one and thus makes it more acceptable and less threatening. Possibly an important consideration if you've had people freak at your knives and tools before. Its for that reason that I carry a SAK secretary (I think it is) as well as my other knives and try to use it unless I need something sturdier or larger.
