In digital graphics, which term refers to the color model that combines red, green, and blue channels to produce colors?

• A. Lossy
• B. Image
• C. file extensions
• D. RGB

Answer: (D)

Colors on screens come from mixing light through three channels: red, green, and blue. This additive process is called the RGB color model, which is how digital graphics produce colors by adjusting the intensity of each of these three colors. For example, combining full red with no green or blue yields pure red, while combining all three at full intensity creates white. When all are off, you get black. This RGB model is fundamental to how digital images and displays work. The other terms don’t describe a color system: lossy refers to a type of data compression, an image is a general term for a picture, and file extensions are just suffixes that identify file formats.
