MATLAB: How to overlay contour plots with a different color map for each overlay

colormapsMATLABmatlab 2015boverlaying contours

I have been able to overlay contours using Matlab 2012b (see the example below) using freezecolors to allow each overlay to have a constant color that is different than the other overlays. But in 2015b freezecolors no longer works. According to this, I shouldn't need freezecolors anymore: http://www.mathworks.com/matlabcentral/fileexchange/7943-freezecolors—unfreezecolors
So I found this, but can't get it to work for what I am trying to do:

Any help to get this to work in 2015b would be greatly appreciated!!!
