[indimg, map] = rgb2ind(YourImage, 4);
newimg = ind2rgb(indimg, map);

You can create up any colormap you want to assign any graylevel range you want to the color you want. Then pass it in to ind2rgb to make a new rgb image, or just call colormap if you want to not create a new RGB image and just view your grayscale image in a pseudocolor image on the display. Do you just want to view it in color with colormap, or do you actually need a new variable in your program that represents the RGB image?
