The eye can see more colors than you can perceive, because of how the signal is compressed to be sent from eye to brain. Yellow and blue light mix and create a white signal, they are opposites and cancel each other out. the other colors mix to create different color hues, but pure blue and pure yellow are special in that they mix to white (all colors, not just themselves) We are unable to perceive 'bluish yellow / yellowish-blue'
this is also why yellow street signs are used in contrast with the blue sky.
Combining blue and yellow pigments does not make white, so I'm going to assume you're talking about combining wavelengths of light. Combining blue (#0000FF) and yellow (#FFFF00) wavelengths also does not uniquely make white. For example, combining green (#00FF00) and magenta (#FF00FF) wavelengths makes white. There are three different primary color wavelength complements that make white.
Edit:
The #RRGGBB representation of color is how colors are often represented in computers. Each pair of digits corresponds to a hexadecimal value for red, green, and blue, with 00 being the least amount of light and FF being the most amount of light.
then you have two signals, that these get combined into. You have a Red (actually pink) + Green - Blue (actually cyan) signal, (magenta-green continuum) and a Red + Blue - Green signal. (blue-yellow continuum) You brain does math on these two signals to extract a red green blue components back out of them, but there are some mixtures that can't be encoded/decoded with that method.
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.
I can't make sense of that in any respect, paint nor ink nor computer displays nor light wavelengths, which is what all the above represent. Yellow-green and blue-green are easily distinguished, just look at lime and aqua. Red signs are more important than yellow ones, green signs are more used than yellow ones.
I wasn't talking about blue green or yellow green. those have green in them. If you mix blue and yellow light your brain 'interprets' it as white. It cannot sense blue yellow.
In the USA yellow signs are used for safety warnings.
Red is ONLY used for stop, green is used for directions, and blue is used for info, white is used for legal notices, but yellow is safety, when visibility is most required.
inks and pigments act different, I'm only talking about the light wavelengths.

I know how pigment and computers work. I'm not talking about that.

it's called the opponent process.
You have three light sensors.
red, green, and blue.
then you have two signals, that these get combined into. You have a Red (actually pink) + Green - Blue (actually cyan) signal, (magenta-green continuum) and a Red + Blue - Green signal. (blue-yellow continuum) You brain does math on these two signals to extract a red green blue components back out of them, but there are some mixtures that can't be encoded/decoded with that method.

The magenta-green you mention is the 'blindspot' the other signal nerve, and the second unperceivable color.

Where the heck is this conversation going? I'm only just now drinking my coffee. I guarantee this is throwing everyone off.. lmao

I provided evidence in the video though

Yes you are on to something. Swedes not so much but where do (((they))) hide their fortune?
Israel became a country why?
