Ah, let me clarify:  If you have a composite video in CMP mode, you get one set of colors.  If you have an RGB monitor and do RGB, you get another set.

I wondered if your device would allow seeing the CMP colors on can XGA monitor, though I am not sure how the device would know which mode to present beyond a push button or something.

This would be similar to how earlier VGA adapters could simulate the composite artifact colors. You could either get pure RGB colors, or go into the artifact mode and see the old CoCo 1/2 PMODE4 type graphics on a VGA monitor with red/blue or blue/red color sets — a very nice feature.
