Does your good generator have gated bars? Post pix of the gated bars from the good one and the new one.
It is pretty hard to get wrong colors from one of these, because if the crystal is at 3579545-15750, there is automatically one cycle of color from left to right. The first burst of subcarrier acts as the color burst, but actually it's changing phase slightly during the burst since the frequency is deliberately different. Then the subsequent bars are each shifted in phase.
One problem you might look for is poor horizontal sync causing the burst gate in your receiver to be offset. Try rocking the horizontal hold of the receiver and see if the hue changes. If so, look for a problem in the H sync waveform out of the generator.
Edit: the 189 KHz is supposed to generate the H sync pulses (when divided by 12) and the gating for the color bars. - So, if this is way off, it might cause some trouble too.
