I’ve heard that monitors and TVs can’t display every possibile color that humans can see. What’s stopping them from just having red, green, and blue pixels, and then just making those go as bright (and as dark) as possible? What’s the limitation?

There’s simply only so many colors you can represent with three mono-color emitters of limited intensity. (Red, Green, and Blue.) With pigments, it’s a similar story. The CMYK system (Cyan, Magenta, Yellow, and Black) used in printing has similar limitations; in fact, the color gamut of standard printing processes is even more-limited than monitors. (This is why your local paint store has a heck of a more than four pigments in their machine; it’s necessary to cover a wider range of colors.)
A pretty short, and funny, summary of how computer colors and printed colors work, in the context of The Pantone System to describe colors, is [here.](https://youtu.be/_b78gAbGwVI?si=AJcllnLu7PFsRPvf)
