The gradient is not a color thing. It has a magnitude and a direction. You may have those for each color plane (R, G, B) or you may have done the gradient on one of the HSV channels if you converted the image to SHV color space. You'd have to take the histogram of one of those images.

Sorry, I don't have any code to share with anyone on SIFT or SURF.
