That is because of RGB to YYrYb or in your case YrYYb. So when you
connect the G with Y you will have a green picture with the values of
the luminance channel (if you had a white phosphor instead of the
green one in your tube you would have a nice b/w picture) but the R
and the B channels will not work with the other components.

You should check the options on your projector. Some are switchable to use
either. If not you need a transcoder which can be found for about $100.
VGA is discrete RGB, while component uses difference signals.

connect the component video to.

As I explained, you need a circuit to "dematrix" the color difference
signals.

Good overview of the formats:
