Color Spaces

A color space is the total range of colors that real devices such as monitors * represented by the sRGB color space or printers, or virtual devices such as a theoretical average monitor* can record or reproduce. This range defines the gamut of the device.

Every real device has a unique color space, and even identical devices (same make and model) have slightly different color spaces, due to factors such as age and production tolerances. These differences increase with variations in user-selected hardware or software settings, such as different monitor resolutions, different printer inks or papers, or even different brightness settings on a monitor.

To improve color consistency and applicability, the International Color Consortium (ICC) and some other companies (Adobe, Kodak, Apple, etc.) For more information on the ICC and color have defined virtual color spaces representing the gamut of virtual rather management in general, see www.color.org. than real devices. We will discuss the advantages of virtual, standardized color spaces later (e.g., Adobe RGB, Apple RGB, sRGB, ...). One advantage of these artificial RGB color spaces is the fact that they are gray neutral, implying that any equal amount of R, G, and B will result in a neutral gray tone. This is not the case for most real device color spaces.
