Is the design an optical color wheel or a color color wheel?

First of all, we must understand what the three primary colors are. Optically, the three primary colors are red, green and blue, which are the three primary colors of light emission. Graphic design is a kind of sensory color, because the light absorbs the color after reflection, so it is not necessary to be so accurate. The three primary colors used in the design plane are red, yellow and blue. In fact, it can't reach the purity recognized by scientists. For example, blue should be (0,0,255). Personally, I think the blue color in the design book is close to sky blue or bright blue, which is about (0,152,255). In that case, why bother about the purity of color? It's just a feeling of color.

This can also be found in the kular palette of ps. How many colors can the human eye recognize? Thousands of them are exaggerated.

The more I look at it, the more confused I am. Actually, don't take it too seriously. It is also a joke that a feeling must be accurate to the extreme. The perfect unification of the two systems (scientists and painters) is also a joke.

No matter what kind of color ring it is, just don't adjust the color brightness too high. After the primary colors are determined, the colors within 60 degrees around the primary colors of the color phase ring are basically harmonious colors. If the contrast is too high, reduce the purity.
