Why do we choose a three-dimensional subspace (RGB) to represent all the colors in an infinite-dimensional vector space? Why is this a good approximation?

When gaming companies boast about their products having backlights with 16.8 million color options, all they are really doing is multiplying the combination of RGB values ranging from 0-255. 256x256x256 = 16777216, and rounds up to 16.8 million

Additive color is a linear combination of red, green, and blue lights with their magnitudes specified by 8 bit integers. It is interesting to see that those three colors can produce a large range of color spectrum. To answer wenhan0112's question, I think the reason that RGB are chosen is that light frequencies at those three places can be produced very cheaply.

I didn't know RGB was chosen because they could be produced cheaply. I thought that resulted from nature. Could you elaborate more on why this three colors can be produced cheaply?

, there are colors our eyes can distinguish that cannot be made with RGB. I wonder what these colors look like!

why is it that light frequencies at those three places of RGB can be produced cheaply? More specifically, what qualities do these three colors have that make them more cheap to produce frequencies with than other colors? I'm more interested in the science about this decision.
