The RGB color model is an additive color system in which red, green, and blue light are combined in various ways to reproduce a broad spectrum of colors. Each color is represented by an RGB triplet, specifying the intensity of red, green, and blue components on a scale from 0 to 255. For example, pure red is denoted as (255, 0, 0), while white is (255, 255, 255), indicating full intensity of all three colors. This model is fundamental in digital imaging and display technologies, as it aligns with the way screens emit light to produce colors. Understanding RGB color codes is essential for web design and graphic applications, enabling precise color selection and consistency across digital platforms.
