From an old similar question (see http://www.mathworks.com/matlabcentral/newsreader/view_thread/83267), getframe is perhaps the most simple way to save a colorbased image by e.g.:
imID=imread('image.tif');
imagesc(imID);
axis image;
colormap('jet');
set(gca,'CLim',[0 255]); %Important!
im=getframe;
image(im.cdata);
imwrite(im.cdata,'nice_image.tif');
Note that you use the command (see "%Important" above)
set(gca,'CLim',[lower upper]);
to set your color limits (lower and upper respectively).

Looks like it was somehow quantized before you saved it. Just don't do that.
