Thank you,
and can I use colormap function for rgb image? because if I didnt convert rgb to gray image, the color in image is not parallel with color in color bar.

You might be able to call it but it won't apply to any true color images residing on your figure. A colormap just doesn't make any sense for an image that is already in color, it only makes sense to apply a color to a gray level.
