I'd think if it's truly anodized color, it should last a long while. I've seen one very, very CHEAP folding knife, with what appeared to be sort of a 'rainbow' anodized finish on it. Turns out, it was a plated finish. The knife was one that a plumber had left underneath my house. It had laid in mud (created by the leak he fixed) for a week or two, before I found it. The plated 'faux anodized' finish basically started peeling off the plain aluminum handles. Ugly.
