* About color temperatures:
There are many different shades that are considered to be "white" for various purposes. One of the
common methods of representing white color is known as the "color temperature". A white color with

appears to have more blue in it.

3D Color Management
In most installation situations, color management will not be necessary, such as in classroom, meeting
room, or lounge room situations where lights remain on, or where building external windows allow
daylight into the room.
Only in permanent installations with controlled lighting levels such as boardrooms, lecture theaters, or
home theaters, should color management be considered. Color management provides fine color control
adjustment to allow for more accurate color reproduction, should you require it.
Proper color management can only be achieved under controlled and reproducible viewing conditions.
You will need to use a colorimeter (color light meter), and provide a set of suitable source images to
measure color reproduction. These tools are not provided with the projector, however, your projector
supplier should be able to provide you with suitable guidance, or even an experienced professional
installer.
The Color Management provides six sets (RGBCMY) of colors to be adjusted. When you select each
color, you can independently adjust its range and saturation according to your preference.
If you have purchased a test disc which contains various color test patterns and can be used to test the
color presentation on monitors, TVs, projectors, etc. You can project any image from the disc on the
screen and enter the 3D Color Management menu to make adjustments.
To adjust the settings:
1. Go to the PICTURE menu and highlight 3D Color Management.
