Five-color color matching

Quick answer：

Five-color color matching refers to a method of mixing colors to create a wide range of hues. It typically involves the combination of red, green, blue, yellow, and black or white. These colors can be mixed in various proportions to create a spectrum of colors, and are often used in art, design, and printing. In color theory, this method is based on subtractive color mixing, where colors are combined to subtract light, resulting in darker and more muted shades.
