Color management allows images and colors to be displayed consistently across a variety of devices. Mozilla recognizes embedded ICC profiles in image files and uses a local color profile to perform the color adjustments. This preference determines if Mozilla should make these adjustments.
The extension Color Management sets this preference through a GUI.
