Does our primary school art textbook say this about the three primary colors?

There are now three theories about the three primary colors, all of which can be proven by books! The three terms are: red, green and blue, magenta, yellow and cyan, and red, yellow and blue. They are explained below:

1. Red, green and blue

are the three primary colors of light, also known as the three primary colors of additive color. The three colors of red, green and blue light add up to a certain proportion to become white, and no light becomes black. The three primary colors of the additive color method are used in televisions, monitors, etc. Relevant information can be found in books about televisions and computers or physics books.

2. Magenta, yellow and cyan

are the three primary colors of pigments, also known as the three primary colors of subtractive color. The three colors of magenta, yellow and cyan are mixed in a certain proportion to make black, and no pigment is white. In fact, it is very difficult and uneconomical to use pigments with extremely high color purity to accurately control the proportions to obtain black. Therefore, black, magenta, yellow, cyan and black must be added for color printing, printing, etc. Corresponding information can be found in books about printing.

3. Red, yellow and blue

This is the longest and most widely circulated saying. Famous artists and art textbooks all talk about it this way. I also learned this way in the past. Yes, this is still written in current books, but it is incorrect! In fact, there is no painter who only uses red, yellow and blue paints! If you friends who are engaged in art still have doubts about this, you might as well try to see if you can use several kinds of paints to make magenta and cyan? What’s sad is the stubbornness of those artists!

If you are not clear about what colors such as red, green, blue, magenta, yellow, and cyan look like, you can refer to the picture below. This is a TV test chart that everyone is familiar with. Its color scale is relatively standard.
