A color code is a notation system that represents a specific color accurately and universally. It is often used in the fields of graphic design, painting, printing, industrial design, and web development. Color codes can be expressed in various formats, such as RGB, HEX, CMYK, and Pantone. The color code is typically composed of numbers, letters, or a combination of both. For example, the RGB color code (255, 0, 0) represents pure red color, while the HEX color code #FF0000 also represents the same pure red color. The color code allows designers, developers, and other professionals to communicate precise colors across different media, without ambiguity or confusion.
