Colours aren't Colours!

Confused? Let me explain...

I was watching Vsauce, my favourite logic channel on YouTube, and he made a good point why "Yellow", while most of you (besides colour blind people, but lets not get into that) and me see it as Yellow, but actually it is not. Heres my explanation:

So, our rays of colour in our brains are Blue, Green and Red. No yellow. So this would go for colours such as black, purple and so on. So the yellow bar is halfway between our Red and Green lines. So the brain will then think, "Oh well, that's a colour I recognize" and pass it on as Yellow, as Red and Green are compliments to each other. Let me say this again: Because the Yellow bar is in-between our Red and Green lines, it confuses our brains into thinking Yellow is one of the lines it stores.

Thus, it goes on for  other colours. So if you were to look at something white, it won't actually be white but your brain will have the Bar of colours, where white is, mix with two other Lines it does store, and sometimes even one! I bet you're asking, why do I see yellow on mobiles, computers and other technology?

Well, the colours on gadgets are made from bars of colour going down vertically,  and all a screen has to do to make you see yellow is the same as your eyes, put the Red bar and Green bar exactly, snugly next to each other. So it depends on which lines in your eyes that mix with whatever colour, to make the colour it wants when you see it. So say, purple mixed with the bars Blue and Green, all the device would have to show was them two bars, Blue and Green, together.

So yeah. If it wasn't for this, everything we saw would be Red, Green or Blue. And colour blind people wouldn't exist, as there was no process in their brains (or ours) to change the colour that was there in front of them to see. So would this help science, such as surgery on the colour blind persons brain to help them see normal?

Well, they would need a transplant. And if they took a donation of that part of brain from a person like you or me who saw normal, then the originally normal person would be Colour blind and the originally colour blind person would see normal. It wouldn't work, people aren't going to be dug out of their graves to retrieve that brain sample.

Unless... scientists borrowed somebody's colour brain part and did research on it. They could figure out what chemicals would be needed, what fluids, and Scientists have plenty of donations to make a replica so powerful, it could be reproduced and the colour blind people... would see normal? My brilliant theory strikes again, haha.

So here was the Vsauce video:
