And then they invented the colour wheel. And the DMD with lots of tiny mirrors. And afterwards they used LEDs and laser diodes...

RGB flashing sequentially is the wooooooorst. Most people can't see it but holy shit i can and it's like random colored strobes flashing everywhere. Bleh

I believe the crt projector doesnt have that issue

I'm going to actually you lol

The reason it works better with CRT is because of the phosphors. They continue to glow, long after the signal has passed over. Check out a CRT slow motion.

Everything to do with display technology involves tricking the eye and relying on persistence of vision which is innate.

I was referring to the spinning color wheel that op was taking about, but yeah the simultaneous three color projector likely doesn't have that problem
