How to correct DRG colors?

I have a DRG in which, for instance, the water features are black instead of light blue.  I've had this happen before, and in my (long ago) notes and it indicated something about repeatedly using Add Colormap until it worked.  Unfortunately that doesn't seem to be the case here -- it is an RGB dataset, which doesn't have a colormap.  The original image is a .jp2, my modified (clipped) version is a .img -- the same problem exists with both.

Attached is a graphic of my DRG.  Any ideas of how to fix?
