ColorImage = repmat(BWImage,[1,1,3]);
The result will be an RGB image whose colors are the same as the black and white image. If you want colors other than shades of grays, then you would need to alter the image.
Or perhaps the answer you are looking for is
colormap hot
or
colormap copper
or any of the other ready-made colormaps.
