COLD(M) returns an M-by-3 matrix containing a "cold" colormap
COLD, by itself, is the same length as the current figure's colormap. If no figure exists, MATLAB creates one.

 load topo
 imagesc(0:360,-90:90,topo), axis xy
 colormap(cold); colorbar

I like your submission. Simple, well written code. Your example inspired me to make a similar one for my Perceptually improved colormaps submission.

You might add a see also for cool, an existing colormap with a slightly different shape in terms of colors.

Regardless, this adds another colormap option. As always, the help is what I'd expect.

Added "cool" to the "See also" section, as suggested.
