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.
