Today’s photography word is:
RGB – is a color mode that adds varying amounts of red, green and blue colors to produce the color in an image, so it is know as an additive color mode. When all the colors are added at once it creates white. Common RGB output devices are TVs, computer monitors, LCDs, and cell phones. Printers start with white paper so it is not a RGB device, it uses a subtractive color mode (typically CMYK).
