Defining colors
The methods and options available for defining colors depend on the type of
PostScript application that you are using.

Color definition notes
CYMK
Photoshop In Photoshop you can choose colors with various color models,
including HSB, CIE Lab, RGB, and CMYK.
Page layout
application
Page layout applications generally use the CMYK color model.
Some allow you to define colors with other color models and
may be able to send that data to the Fiery in those other color
models. Generally, however, CRDs (which affect only RGB
data) do not affect colors defined in page layout applications.
For predictable results with CMYK colors, use the CMYK
Color Reference when defining colors in page layout
applications (see “Using color matching tools with PostScript
applications” on page 4-28).
Illustration
application
All illustration applications use the CMYK color model.
Although you may be allowed to define colors using other color
models, these applications generally send only CMYK data to
the Fiery.
For predictable results with CMYK colors, use the CMYK
Color Reference pages when defining colors (see “Using color
matching tools with PostScript applications” on page 4-28).
Different versions of Illustrator support color models slightly
differently (see “Note about color models in Adobe Illustrator”
on page 7-64).
