      XcmsFloat L_star;
      XcmsColor *color_return;

ccc	Specifies the CCC. The CCC's Client White Point and white point adjustment procedures are ignored.
hue_angle	Specifies the hue angle (in degrees) at which to find maximum chroma.
L_star	Specifies the lightness (L*) at which to find maximum chroma.
color_return	Returns the CIE L*a*b* coordinates of maximum chroma displayable by the screen for the given hue angle and lightness. The white point associated with the returned color specification is the Screen White Point. The value returned in the pixel member is undefined.
