Can someone explain to me how colors work? Why do I hear people say that X color has low energy and X color has high energy and whatnot? How do this shit work?

In the name of science, I'll bite. Brown is just dark orange. Also, pink is light red.

Pink is light magenta.
Purple is dark magenta.

All light has the same "energy", it's all about how much of that energy is transmitted over some unit of time

There are 3 receptors for color vision in the retina, along one kind of receptor for light vision. The color vision receptors send signals depending on the wavelength of light received. They are most sensitive to the colors Red, Green and Blue, and at some wavelengths their responses overlap.
With these signals the brain processes a mental image and comes up with colors. How this is done is not known. For the color magenta specifically both the red and blue receptors are stimulated at the same time, this color does not correspond with a specific frequency on the light wavelength spectrum.
>low energy, high energy
This is a misconception, but related to the type of color yielded by a certain wavelength. In the case of magenta, you could say it's both a low and high energy color, thus it's not appropriate to call them that.

Light comes in discrete packets called photons. A red photon has less energy than a green one which has less energy than a blue one.

why do green appear brighter than blue if it has less energy? make no sense

Because luminance is a separate thing from color. Higher luminance means brighter regardless of what color you're talking about.

Since we are talking about brown and pink, these are variations in lightness. The components of color are hue (the kind of color itself), lightness also called value (how white or blackish the color is), and saturation (the perception of color intensity at its purest). Brown is a dark kind of orange, and pink is a light kind of red. Saturation is tricky, since the most saturated color varies in lightness depending on the hue, being a very pure yellow a lighter color than a very pure blue.
Also the complete gamut of physiologically visible colors, i.e. all the possible colors we can see, is larger than what monitors can output, that is also larger than what has been standarized as the sRGB model, and the sRGB model is larger still than the colors that can be printed.

wonder why we've been stuck with a dogshit system like rgb when we should already be having pixels in our computers that display every monochromatic color in the spectrum

Your eyes only have receptors for red, green and blue light. You literally can't tell the difference between an RGB image and an image that emits all colors.

Two problems:
1. Violet light is incredibly hard to produce artificially, most of the time you can only use prisms to see it faintly, and even then it's not enough
2. Pure, monochromatic Violet light is harmful to human eyes, even moreso than Blue light, it carry the highest energy so far, so equipping our screens with violet subpixels would be detrimental for our eyes
It is like the other anon said, the RGB system is good enough as it is.

This is incredibly, hilariously wrong. You might be amazed to learn that eyeballs evolved not to be burned out by light.

The Munsell color system explains this. Green and yellow are the brightest (most saturated) at higher lightness, compared to blue which is similarly purest at lower lightness. The capacity of a color to be saturated in relation to lightness is not uniform, and this is one of the shortcomings of sRGB which assumes all colors get saturated in the same proportion and causes problems if you want to recolor a picture.

Then you tell me anon, go to a laboratory and ask to see pure violet light with your naked eyes, see how that turns out for you.

Yellow is a spectral color. The yellow in screens is a fake yellow made from triggering the M and L receptors in a similar proportion a yellow wavelength would.

E = hbar * f
Frequency IS the color of light that you observe when interacting with a plane wave.

Photons themselves have very little energy, light is the transmission of energy through the photonic field, like sound is the transmission of energy through atoms
