• Gamut. In color reproduction, including computer graphics and photography, the gamut, or color gamut ( /ˈɡæmət/), is a certain complete subset of colors.
• Grayscale. A grayscale digital image is an image in which the value of each pixel is a single sample. Displayed images of this sort are typically composed of shades of gray, varying from black at the weakest intensity to white at the strongest, though in principle the samples could be displayed as shades of any color, or even coded with various colors for different intensities.
• GUI. A graphical user interface (or GUI, sometimes pronounced "gooey") is a method of interacting with a computer through a metaphor of direct manipulation of graphical images and widgets in addition to text.
