Use fft2 on each of the colour planes in turn, for example
Ft_image(:,:,1) = fft2(Image(:,:,1));
Ft_image(:,:,2) = fft2(Image(:,:,2));
Ft_image(:,:,3) = fft2(Image(:,:,3));
(assuming that you don't want the Fourier transform in colour space - I don't think that would make sense).
I don't know about the fractional Fourier transform.
