How to change color settig for imagesc command?

Hi everybody, I have wrote a program in MATLAB and when I execute my program on two different computers, the colors of the output figures are not the same, see the attached two figures. Does anyone knows how can I solve the problem? I am using two different versions of matlab. The first image (named CP1) is created by MATLAB 2012a and the second image (named CP2) is created by MATLAB 2012b. Thanks for your response.

imagesc() makes use of the current colormap . You should choose a particular colormap to use, such as

colormap(hot(256))
