• Color Temp: Select Color Temp from the Display Color - Common Settings menu to
adjust the color temperature. Color temperature establishes the “color of gray” by
adjusting the 75% white point to various color points.
What are “color points?” A “color point” is an x/y coordinate pair that defines a
color’s location on the standard CIE chromaticity graph, shown in Figure 4-7. (CIE
stands for “Commission Internationale de l’Éclairage” (International Commission on
Illumination), the organization responsible for color measurement and management
standards.)

• Simple: Select Simple mode from the Color Temp menu to choose one of five color
temperature presets: 3200K, 5500K, 6500K, 7500K and 9300K. The default setting,
6500K, is appropriate for most situations. Higher settings produce a “bluer” picture;
lower ones impart a reddish hue to the image.
Table 4-2 lists the x- and y-coordinates for each color temperature preset in
“Simple” mode.
