Well, it really depends on your personal preference.
I have multiple pairs in different colours because I like to match them with my outfits but that's just something I enjoy doing, similar to the way I paint my nails a different colour to match every outfit.
I think that subtle additions to your look can really make you stand out so if you like that kind of thing try to mix it up little sometimes or if not just keep it classic with a dark pair of shades which pretty much go with anything anyway. X
