Operation

PCE provides the ability to define a custom color gamut in terms of a “white point” and primary (red, green, blue) and secondary (yellow, cyan, magenta) 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 4-12.(CIE stands for “Commission Internationale de l’Éclairage” (International Commission on Illumination), the organization responsible for color measurement and management standards.)

•RGB (Red, Green, Blue)/YCM (Yellow, Cyan, Magenta): To precisely adjust the primary or secondary color points associated with the custom color gamut, choose RGB or YCM respectively from the PCE sub-menu. Each control operates only on the color specified. Surrounding colors are linearly interpolated based on their distance from each of these colors.

•White Balance: To precisely adjust the white point associated with the custom color gamut, choose White Balance from the PCE sub-menu. These controls operate

identically to the color point controls.
