Nobody is talking about paint, or pigments, or color charts - or the representation of those things on computers (which you are also confused about). Try to keep up.
Blue and yellow are on opposing sides of the spectrum of visible light. Light, as in photons and electromagnetic wavelengths. Physics, not RGB color schemes.
That's not actually true though, because red is on the end of the spectrum. It's neither blue nor yellow.
If you study the computer representation of color, you'll see that it's designed around wavelengths and not pigments. That's why I used it instead of pigments (which I wrote clearly in the message). The RGB representation just provides an easily understandable model of light.
