RGB stands for Red, Green, and Blue, which are the primary colors of light used in additive color mixing.
In this color model, various colors are created by combining different intensities of these three primary colors.
When combined at full intensity, they create white light. This is because, in additive color mixing, the combination of light of all colors results in a bright, white hue, while the absence of all light results in black.
RGB is widely used in digital displays, such as monitors and televisions, where pixels emit red, green, and blue light at varying intensities to produce the full spectrum of visible colors.
By adjusting the intensity of each primary color, a wide range of colors can be created, which is fundamental to digital imaging and color representation on electronic devices.
