Object Recognition using SIFT and colour

I am performing object recognition on chocolate bars and am using sift to do so however if the bar is similar to other with the different colour, recognition is not working correctly. Is there a way of using sift with colour as from the research I conducted sift works best on grayscale images.

There are demos for SIFT in the Computer Vision System Toolbox http://www.mathworks.com/products/computer-vision/
