Hue/ S aturation/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 4-12), 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.

S aturation Controls
R S C™ (Runco S mart 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 RGB Adjust menu (described on page 44).
