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”).

COLOR ADJUSTMENT BY X,Y: Use

this submenu if you want to create, alter 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 (see Figure 3.19)—changing either or both of

these numbers will change the hue of the color, and relocate the “triangle” for possible colors. For example, changing the x/y

coordinates for red may move the color closer to orange or closer to violet, which will in turn affect 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 Advanced Image Settings menu.
