Gfx.color management.mode

From MozillaZine Knowledge Base
Jump to navigationJump to search


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.

Possible values and their effects


Disable color management.


Enable color management for rendered graphics.


Enable color management for tagged graphics only. (Default)

Note: These values apply to Firefox 3.5 and SeaMonkey 2. In previous versions, color management was disabled by default via the boolean preference gfx.color_management.enabled set to "false".


  • Without a properly calibrated monitor and a correct color profile, color management may actually make colors look worse.
