An additive color model that represents colors as combinations of red, green, and blue light, used in all digital screens.
RGB is the standard color model for digital displays. Each channel (red, green, blue) is typically represented as a value from 0 to 255 (8-bit), giving a total of 16.7 million possible colors. The hex color notation (#FF5733) is a shorthand for RGB values in hexadecimal format. RGB is device-dependent, meaning the same RGB values can appear differently on different monitors unless color management is applied. It forms the basis for web colors (CSS rgb() function) and is the native color model for most image editing software.
