color_correction_volume is a brush entity available in all Source games. A color correction lookup table is faded in or out when a player enters or leaves its volume. Fade time is configurable.

Bug:This entity does not work in Counter-Strike: Global Offensive.

Workaround:Use trigger_multiple brushes to output commands that disable an active color_correction entity and enable a separate color_correction entity in its place; upon touch.

Note:If a color_correction entity has a value of -1 in both lookup falloff start and end distance, and is active as soon as you spawn, then enable that entity's "Master" flag. All other color_correction entities must be set to "StartDisabled" as seen in their keyvalues for this to work correctly.

Bug:This entity affects all players connected in multiplayer, even if only one entity comes in contact with it. Fixed in Black Mesa.  [todo tested in?]

Todo: Test in , which has more support for custom color correction
