Well, I don't care much about things *matching* but if I've found a thing that does whatever it is that it is supposed to do in a way that I find useful then I want more like it, maybe in different colours. Like, say, shoes - I don't much care what my day-to-day shoes *look like* but I care that they are comfy. I *know* that these ones are comfy but when they wear out I will have to try on dozens of styles and guess which will be most comfy (and likely end up buying and discarding as useless at least one pair); if I could just buy the same style then I wouldn't have that hassle.
