There's a couple layers to what's going on here. I'll try to help break them down.

Layer #1, you need to get the goddamn RYB color model out of your brain, forever. Remove it permanently from your mind. It is NOT a scientific model and it has been outdated for hundreds of years. I don't CARE what you were taught, even in professional art schools. I don't CARE about what X Y or Z thing some person said, the RYB model is OBJECTIVELY just wrong, period. We were all fed this bullshit in school but you need to unlearn everything about RYB.

It's a relic from a time when we didn't have scientific tools to tell what the 3 primaries really were, so some guy gave it his best guess, and got 2/3 of them right. There are only TWO reasons you should EVER use RYB.
1) Because RYB compared to RGB has a gamut which skews toward giving you more shades to work with for beiges, browns and human skin tones. (But there's still no particular reason to favor RYB for this. You should learn how to paint using primaries you make up on the fly, that will give you the most detail for whatever you wish to paint.)
And 2) Just because yellow is a happier, more fun color than green, so you might arbitrarily use it just cuz you're designing something that happens to look better with yellow.

It's RGB, nothing else matters. Even CYM isn't REALLY about those colors. We only use them because paints work in an opposite, inverted way compared to pure light, and CYM just happens to be the opposite of RGB.

Layer #2
>red, yellow, and blue, mixed together can make everything.

Sorry nah. R + Y + B won't even give you black, it gives you a gross swampy brown. The most optimal primaries to use to get the most colors possible (in paints) are yellow, cyan and magenta, which is why your ink printer uses them.

1/2

2/2

CYM is what should be taught in art schools. RGB for every other purpose. Also, even CYM can't give you EVERY color, because this is impossible with only 3 primaries using paints. But CYM gets like 95% of all colors so we call that good enough.

Mixing paint is a flawed and messy process in the first place, compared to mixing pure light directly. It's actually NOT the case that if you take 2 identical-looking paints from 2 different paint manufacturers, that they will mix exactly the same way. They will most likely mix with very subtle differences. Paints are physical liquids, and they change structure when mixed. Paint manufacturers do their best to create colors that mix together perfectly but ultimately this isn't actually possible. Physical matter is imperfect.

Layer #3
>Mixing red and green shouldn't be able to make orange

Red + green makes yellow, which would give orange if one of your 2 base colors is slightly off. Red and green are NOT opposite colors.** Purple and yellow are NOT opposite colors. You have to unlearn this.

** So we're talking about paints and light, but just as a side note, red and green are opposite colors but ONLY psychologically. Red/Yellow/Green/Blue are the "psychological primaries" because you have filters in your eyes that compare how blue vs yellow something looks, and another that compares how red vs green something looks. So mentally, we internally view green as red's opposite. But TO BE CLEAR that's only psychological. When we speak of mixing paints or light, green is absolutely NOT the opposite of red.

I'm going to bed but lemme know if u got questions or w/e.

Mixing yellow and blue doesn't make green. Don't be a fucking idiot. It makes bluish yellow.

You can see this by just holding up something yellow to one eye and blue to the other and looking at the overlap.

Dipshit can't even see bluish yellow. Look at him and laugh.

RGB is additive. It is based on cones in the human eyeball. For example, when light reflects off of a carnation, an electromagnetic wave with a distinct waveform emanates from it. When this EM wave hits the eye, it is lensed onto the retina, and cones interpret this waveform by measuring how 3 different types of cones react. These are long, medium and short cones. And with this, the eye is essentially performing a mathematic transformation on the waveform, breaking it down into percentages of long, medium and short. So with the carnation waveform, it would interpret the wave as 100% long, 50% medium, and 50% short. This is a perception known as 'pink'. Pure, isolated reaction of the long cones would produce the perception of red, the medium, green, and the short, blue. So these are called the red, green and blue cones. If you want to display a carnation on a computer screen, you don't need to recreate the EM wave. You just need to create a simplified version of the waveform by shining lots of red, a bit of green and a bit of blue, and the human eye will resolve it to the exact same perseption of 'pink'. Thats why screens use RGB. It is actually a clever device that creates the illusion of the EM waveforms of every day objects that directly stimulates the human eyeball. But it only works on humans 3 pronged vision. Not on other creatures with different cone configurations. If a dog or a parrot or an alien looked at a computer screen, they wouldn't see an accurate recreation of colors.

RBY is subtractive for a simple reason.
Blue paint is blue because it chemical makeup of the paint means that it absorbs the wavelengths of light that we would percieve as red, while creating a waveform that we would interpret as mainly blue with a bit of green. Yellow paint is yellow because it absorbs the wavelengths that we would interpret as blue, while creating a waveform that we would interpret as red and green.
When we mix blue and yellow paint, we have created a mixed substance that can now absorb both red AND blue wavelengths. So the wave that comes off it would only be interpreted as green.
As you mix paints together, you are adding to the absorbative properties of the mixture, and taking away elements of the light that is reflected. Whether it is the red, green or blue components. Hence subtractive.
