For me, it's mostly about the style of bag I need rather than color. But I did buy a bright red Longchamp a while back and I also want a dark blue bag back in my collection. During the dark winter months I seem to gravitate towards bright colored bags and, for summer, I even carry patterned designs (which I don't do any other time of the year, ever). So I guess it's 50/50 between style/color.
