What is RGB Color Mode?

RGB: Red, Green, and Blue

The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

The term RGBA is also used to mean Red, Green, Blue, Alpha. This is not a different color model, but a representation; the Alpha is an additional channel (not component) used for transparency.

The table below shows the result of combining Red, Green, and Blue light sources:.
