Impossible to display two binary maps with different colors with subplot

I am typing to plot two binary maps (A & B) with two different color map (map1 is red and map2 is green) in one figure using the subplot command. My codes goes as follow:

subplot(121) imshow(A,map1); subplot(122) imshow(B,map2);

Strangely enough, Matlab always display the two maps in the color of map2. This is not the case when the two maps are displayed in separate figures. How come?

Thanks for your help

There is only one colormap per figures.

I recommend you use the FEX contribution "freezeColors" http://www.mathworks.com/matlabcentral/fileexchange/7943-freezecolors-unfreezecolors
