Runco Q-750D operation manual Hue Saturation

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.

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).
