Color in three color values

Quick answer：

Color in three color values refers to specifying a color using a combination of three numerical values that represent the intensity of each of the primary colors (red, green, and blue). This is commonly used in digital color systems, such as those used in computer graphics and color printing. The most common formats include RGB (Red, Green, Blue), where each color's intensity is represented by a number from 0 to 255, and CMYK (Cyan, Magenta, Yellow, Key/Black), which is used in printing.
