Cie 1931 Chromaticity Diagram - Runco XtremeProjection X-450d Installation & Operation Manual

Operation
• 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 (with the X-400d/X-450d,
this is the only choice) 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.
