Set color map color range

I have a 3D plot using patch and the default colormap is jet as I am using R2014a.So I use

cMap=hsv(250); colormap(cMap); caxis([min(M(:)) max(M(:))]);

But when the value increase the color changes from deep blue to light blue then to deep red. It is not desirable for me as I want the color change from light color to deep color when the value increase. So how can I adjust the colormap so that it changes from, say light blue or white to deep red as the value increase? Thank you.
