Color Blindness a Thing of the Past?

My hubby is color blind.  A friend of mine sent me an article today discussing research into color blindness.  Apparently scientist Jay Neitz from the University of Washington is experimenting with squirrel monkeys and enabled them to see color.  Specifically they were able to respond to red signals that they were not able to respond to before.  Of course this involved injecting their eyes with a virus.  That doesn't sound so pleasant and who knows what the side effects are.  But the over ramifications of a cure to colorblindness and possibly even total blindness I think is pretty amazing.  If you want to read more about the study you can check it out here: http://www.wired.com/wiredscience/2009/09/colortherapy/
