    One thing you could do is reverse the color table. So, say that you have a grayscale image displayed in ENVI. You could right click on the layer containing those data, and choose Change Color Table > More. In the resulting dialog, you'll see that the B-W LINEAR color table is chosen. You can click the Reverse button to the right to inverse the color table. - Pe
