Operation 41
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 adjusent 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 adjusents.
To adjust the settings:
1. Go to the  PICTURE menu and select  3D Color Management .
2. Press  Mode/Enter  and the 3D Color Management  page displays.
3. Select  Primary Color  and press  /  to select a color from among Red, 
Yellow, Green, Cyan, Blue, or Magenta.
4. Press   to select  Hue and press  /  
to select its range. Increase in the range 
will include colors consisted of more 
proportions of its two adjacent colors. 
Please refer to the illustration to the right 
for how the colors relate to each other. 
For example, if you select Red and set its 
range at 0, only pure red in the projected 
picture will be selected. Increasing its 
range will include red close to yellow and 
red close to magenta.
5. Press  to select  Saturation and adjust 
its values to your preference by pressing  / . Every adjusent made will reflect 
to the image immediately. 
For example, if you select Red and set its value at 0, only the saturation of pure 
red will be affected.
• Saturation  is the amount of that color in a video picture. Lower settings produce 
less saturated colors; a setting of “0” removes that color from the image entirely. If 
the saturation is too high, that color will be overpowering and unrealistic.
6. Press   to select  Gain and adjust its values to your preference by pressing  /
. The contrast level of the primary color you select will be affected. Every 
adjusent made will reflect to the image immediately. 
7. Repeat steps 3 to 6 for other color adjusents.
8. Make sure you have made all of the desired adjusents.
