Runco D-73D operation manual Color Temperature Presets and Associated Color Points

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 (5500K, 6500K, 7500K or 9300K) mode from the Color Temp menu (with the D-73d, this is the only choice) to choose one of four color temperature presets: 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 4-2lists the x- and y-coordinates for each color temperature preset in “Simple” mode.
