Additional Information
RGB color space, also known as the RGB color system, allows us to construct all colors based on combinations of Red, Green, and Blue. Each of these colors uses 8 bits, resulting in integer values ranging from 0 to 255. This enables 16,777,216 possible colors (256 * 256 * 256).
The RGB value consists of three numbers, each within the 0 to 255 range. The magnitude of each number represents the brightness of red, green, or blue light. By varying the proportions of these three colors, we can create different hues. Any color on a screen can be expressed using an RGB value. Hence, red, green, and blue are often referenced as the primary colors of light, denoted as R (red), G (green), and B (blue).
