difference in corsair vengeance ram colours?

Solution
Essentially all RAM is the same if it has the same speed and latency, but some models overclock better than others. That said, if they're both Corsair Vengeance it's just the color and otherwise they're the same.
Hi Shaun88 , you will find that there is a variety of colors to give people options when choosing their ram with a particular color scheme in mind,
basically you can get a 1600mhz kit the same speed and latency in multiple colors to suit the look of your board or 1866 or 2133 and so on.
so if you have a motherboard with black and blue colors you might go with the blue colored ram or a red and black motherboard you might go with the red colored ram etc etc
