Operation
• Hue/Saturation/Level: PCE provides the ability to define a custom color gamut in
terms of primary (red, green and blue) and secondary (yellow, cyan and magenta)
color hues, saturation and level (brightness).
Each control operates only on the color specified. Surrounding colors are linearly
interpolated based on their distance from each of these colors. In the CIE 1931 Yxy
coordinate system (see Figure 4-8), Hue rotates the color coordinates around the
white point, Saturation adjusts the coordinate's distance from white and Level
adjusts the luminance (Y) of the color relative to white.

Figure 4-8. CIE 1931 Color Coordinate Diagram and Effect of PCE Hue and
Saturation Controls
• RSC™ (Runco Smart Color): Set RSC to On to to improve the accuracy of flesh
tones and increase color saturation, without sacrificing the purity of other 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 Gain controls in the Display Color menu (described on
page 60).
