It's exactly the kind of problem I've tried to explain, it's caused by the
three luma lines that don't  mix very well. Get a little pot (are they
called "trimmers"?) and send a luma line through it, turn the pot to see if
you can get good colors. If it's not good enough, try with the other two
luma signals.

BTW... I've a 2600jr that gives such a beautiful, vivid image via RF that I
don't want to modify it for composite video because it's much better than
my other, modified 2600!
