Color Adjustments by X/Y, and Color Saturation —
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color performance or
"gamut". Sometimes known as Comprehensive Color Adjustment™. 2) Factory-
defined primary color levels, which ensure a specific color performance from
projector-to-projector, can be calibrated in the Service menu only. If you suspect
alteration of these defaults, the factory settings can be recovered with selection of
"Reset to Factory Defaults?" in the Color Primary Settings submenu accessed via
the Service menu (password-protected).
From the factory, the projector can
utilize any of the three pre-defined color
performance settings identified at right
(default=Max Drives), or colors can be
driven on the basis of color temperature
(Figure 3.21). For most applications, one
of these gamuts will produce accurate
and realistic colors from a variety of
sources. They can be applied at any time
in the Advanced Image Settings menu
("Select Color Adjustment"), and are not
adjustable.
DEFINING "USER" COLOR GAMUTS:
defined "Select Color Adjustment" options exactly suit your needs. For example, you
may require a unique color gamut (range) for a single projector or application, or you
may need to precisely match colors across multiple adjacent displays. In such cases,
use the Color Adjustments by X, Y or Color Saturation submenu to define the precise
hue of each primary color 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 that the two menus differ only in their user interface, so use whichever menu
best suits your needs and application. A color meter can help with adjustments.

Color Adjustments by X, Y — Enter known x/y coordinates from the chromaticity
graph.

Color Saturation — Adjust color slidebars and judge image color by eye or
meter.
A user-defined color "adjustment" can be applied by selecting it in the Advanced
Image Settings menu ("Select Color Adjustment").
