How can I change the color of a mesh at specific indices?

I have a mesh plotted in a GUI via the following command:

handles.mesh = mesh(X,Y,Z,'facecolor','b',... etc.

I've plotted it in 3d purely for aesthetics; the raw data is 2-dimensional. I then periodically update the plot's values by virtue of a timer, and the set command, shown here:

set(handles.mesh,'ZData',PSD2);

This is what the mesh looks like (ignore that floating label):

What I would like to do now is highlight (change the color of) specific peaks that are of interest to me. If I have a vector that contains the index of the peaks that I'm interested in, is there a way I can use that vector to color the mesh just near those indices?

I.e. -- if I want the peak that is (currently) at 4000 Hz to be red, while the others remain yellow, can I do this?

Thanks,

-Will

Yes. See the CData property here
