I heard the bell:

to this:

Three colored cats.
Cats have only two colours of wool - red and black. White is the absence of color.

Would you be surprised to learn that black is the absence of color, and white is all colors? If not, then keep talking about chromosomes, you do so well)))

There are two color theories - one for light (as on a monitor, where white is a mixture of all colors), the other for pigment (color, melanine, and so on, where everything is exactly the opposite). And when you confuse additive theory with subtractive theory, trying to ridicule a person who understands the pigment, then it becomes ridiculous.
