7.2 Setting a white point or color temperature
After enabling RealColor™ set the color temperature in the menu PICTURE >
REALCOLOR > TEMPERATURE
. Values between 3200K and 9300K can be
selected. These color temperatures are tracking the “black body curve”- the
black curved line in the center of CIE Chart in Figure 7-1. The default is the D65
illuminant at 6500K.
The white point can also be set to a custom value defined by an x, y coordinate
not linked to the black body. Go to menu
PICTURE > REALCOLOR > X-COOR-
DINATE and PICTURE > REALCOLOR > Y-COORDINATE to change the white
point.

7.2.1 Defining the system color gamut
All colors visible to the eye are defined by CIE Chart in Figure 7-1. The boundary of the colors
the projector can display is called the system color gamut. The white triangle in the figure is
an example of a system color gamut. By default the projector has the widest possible system
gamut.
The system color gamut cannot be expanded outside native color gamut.
It may be desirable to change the system color gamut of the projector to:
• Color-match multiple projectors.
• Meet defined color standards, like REC 709.
• Create a special “look” to the image.
Before the system color gamut can be changed, the desired RealColor™ mode has to be
defined. To change the RealColor™ mode please go the menu
PICTURE > REALCOLOR >
DESIRED VALUES > DESIRED COORDS MODE .
RealColor™ has to be enabled for the desired system gamut to be applied. Go to menu
PICTURE > REALCOLOR > COLOR CORRECTION to enable RealColor™.
After RealColor™ is enabled and the desired color correction mode is selected, please go
the menu entry
PICTURE > REALCOLOR > DESIRED VALUES to change the color points
to your desired system color gamut .
