Section 3: Operation
Defining User Color Gamuts
In some cases, you may find that none of the pre-defined "Select Color Adjustment" options exactly suit your
needs. For example, you may require a unique color range or gamut for a single projector or application, or you
may need to precisely match colors across multiple adjacent displays. In such cases, use the
Adjustments by X,Y
component (red, green, blue, and white) used to generate the millions of colors produced in displays. You can
create up to four custom color gamuts (User 1, 2, 3, or 4) with these adjustments.
NOTE:
The two menus differ only in their user interface, so use whichever menu best suits your needs and
application.

A user-defined color "adjustment" can be applied for a source by selecting the desired "User" option in the
"Select Color Adjustment" list accessed in the
Color Adjustment By X,Y Secondary Menu
Use this secondary menu if you want to alter, add or copy a color gamut (i.e., "color adjustment"). Controls in
this menu define the precise hue of each primary color component (red, green, blue, and white) used to
generate the millions of colors produced in displays.
The x/y coordinates for each color define its location on the standard CIE chromaticity graph (refer to
3-29). Changing either or both of these numbers changes the hue of the color, and relocates the "triangle" for
possible colors. For example, changing the x/y coordinates for red will either move the color closer to orange
or closer to violet, which in turn affects all displayed colors having a red component. Adjust the slidebars or
enter new specific coordinates as desired to define or change up to four "User" color gamuts needed for your
environment and applications. Apply at any time in the
