What is your definition of the "Color" gradient? As you know, color is a 3-dimensional property, like RGB or HSV. Do you want imgradient() of the gray scale image or the V image, or of the Hue image? Or the saturation image? Please give a mathematical definition.

You didn't answer my question so all I can suggest is to look at imgradient() or imgradientxy().
