Reply to comment by scooby1st in When people refer to “training” an AI, what does that actually mean? by Not-Banksy

Yellow isn't a primary color. The primary colors are red, green, and blue.

There are primary colors of physical pigment then there are primary colors of light.

When people learn the primary colors in school it's almost always in art class when mixing paint.

So kinda confidentlyincorrect but not entirely

There's additive color and subtractive color. The set of red, blue, yellow, is primary for neither. Additive primaries are red, blue, green. Subtractive primaries are cyan, yellow, magenta. If you're mixing paints you're working with subtractive color and thus the primary colors are cyan, yellow, and magenta. not red, blue, and yellow.

The info is incorrect no matter the context.

I don't care enough about colors to keep going but it's been red blue and yellow since the 1600s

Well no. That's been incorrect since the beginning of time. This is a factual scientific topic. There is a correct answer and incorrect answer. It's not up to preference or opinion. Printers use cyan, magenta, and yellow, because those are the subtractive primary colors. If you used red, blue, and yellow, you can't actually produce the rest of the colors with those. Since red and blue aren't primary for subtractive color, but rather iirc secondary. People being wrong for a long time doesn't mean they're right.

You can't produce all colors with any set of three primaries..

That's literally what primary colors are. How do you think screens and printers are able to produce every color despite only working with 3 of them? Because that's literally what primary colors are.

Yes. You do realize our eyes only have three kinds of cones right? Rgb are the primary colors lol. Cmy if you're looking at subtractive colors. Using these three colors, you can create every other color. Rgb for light/additive, Cmy for ink/paint/subtractive.

Rby is not primary in any sense of the word.

Yeah that's just incorrect. Additive primaries are RGB. Subtractive primaries are CMY. You're free to deny the facts all you'd like, but this is just an objective scientific thing.

Some childrens tv shows or media programs stating incorrect information does not make it correct. Additive primaries are RGB, subtractive primaries are CMY. The idea that RBY are primary colors is a popular misconception, but is incorrect. It has it's roots in art classes prior to proper scientific investigation of color, light, and modern technology. If your goal is art history, then yes, people in the past incorrectly believed that the primary colors (both additive and subtractive) were RBY. They were wrong. Just as people believed the earth was flat, yet were wrong.
