If you mod a 16-bit NTSC console for 50 Hz it outputs 50 Hz NTSC; the NTSC and PAL graphics chips are separate models so the color encoding is still NTSC. It's sort of the Bizarro version of the 60 Hz PAL they use in Brazil.

I thought about this, but the Genesis graphics chip actually outputs RGB to a Sony CXA composite decoder, which supports both PAL and NTSC, which is determined by an oscillator. On the Genesis, when I shift to 50Hz the entire system bus changes, so I would think that would change the frequency going into the CXA chip as there's only one oscillator in the system. I'll need to scope it out, perhaps it still stays the same..
