Operation
•Advanced Color Enhance (ACE): Use the Advanced Color Enhance (ACE) controls to customize the stored color space characteristics. To do this, use the 
or 
button to select a component color (Red, Green, Blue, Yellow, Cyan or Magenta).
For each component color, you can adjust the following:
•Limit: This slidebar adjusts the intensity – also known as luminance – of a given color.
•Saturation: This slidebar adjusts the color saturation level – the amount of that color in a video image. Lower settings produce less saturated colors; a setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be overpowering and unrealistic.
To restore the color space settings to their
•Gamut: Under most conditions, the White Balance and Advanced Color Enhance (ACE) controls in the Calibration menu are adequate for producing accurate and realistic colors from a variety of sources.
In rare cases, though, you may need more precise control over the Vision 65/75 display color gamut (range). For example, you may require a unique color gamut for a given projector or application.
The Vision 65/75 enables you to define the precise hue of each primary color component (white, red, green and blue) used to generate the millions of colors produced in displays. You do this by specifying x/y coordinates and luminance values for each primary color component.
The x and y coordinates for each color define its location on the standard CIE chromaticity graph, shown in Figure
