Thanks Everyone!, that was it, My colors are back to Normal!

thanks albert I'm gonna try that

created this in photoshop, but i got it pretty much exact....

In Color Mode - My 2600 shows only a few colors on the screen, I get the full grayscale, plus a few additional colors, like green and yellow, and white (which probably doesn't count anyway). B&W switch does convert it to B&W. example like river raid I have the yellow jet, but no blue water, it's grey. Any suggestions? I've completely cleaned the system in and out already, this seems to be the only problem, the gameplay is fine. I'm not using a RF switchbox either, I have the adapter on my TV. I have used a working RF adapter, but got the same color problem. Thanks -mab
