primary color
A primary color is a color that is independent of each other, which can make all kinds of colors by mixing colors. An independent color means, for example, that in the case of three primary colors, it is impossible to create a third color that remains after mixing the two. In human eyes, primary colors are often three color combinations. For example, in a television monitor or a light source, the three primary colors of the additive mixture, which superimpose the lights of different colors to create a new color, are usually three colors of red, green, and blue. In addition, the three primary colors in the case of the subtractive mixing performed when the coloring agent is mixed or the color ink is added to the color printing is three colors of cyan, magenta, and yellow.
