Now, yes, that is a picture that looks quite similar to Colette... however I'm sure there are many blonde girls in anime, and to be honest it's hard to tell without any of her signature identifying characteristics - chakram, wings, stockings, outfit. All we have left to go by is hairstyle, and while Colette's does tend to be somewhat generic, it does seem to match...
A very close call. Indecisive unfortunately, but if you want to believe, then I don't think that would be a problem. Oh, and as I recall, Colette does have blue eyes, another step in the right direction.
