4. A dialog box appears in which you can define the
color temperature. You can define the color
temperature in Kelvin units or CIE (x,y) co-ordinates.
In Kelvin units, you can change the color temperature
value from 5000 K to 9900 K.
In (x,y) co-ordinates, you can change the values from
0.250 to 0.360.
Note:
When defining a color temperature in x,y co-
ordinates, it may be possible that the target
luminance
cannot be reached with the given settings
of x,y.
The color temperature, however, will match the given
x,y co-ordinates.
