Your scripts can use the same range of colors that are available from the Photoshop CS3 user interface. 
Each color model has its own set of properties. For example, the 

RGB color

 

(RGBColor/RGBColor)

 class 

contains three properties: red, blue and green. To set a color in this class, you indicate values for each of 
the three properties. 

In VBScript and JavaScript, the 

SolidColor

 class contains a property for each color model. To use this 

object, you first create an instance of a 

SolidColor

 object, then set appropriate color model properties for 

the object. Once a color model has been assigned to a 

SolidColor

 object, the 

SolidColor

 object cannot 

be reassigned to a different color model. 

The following examples demonstrate how to set a color using the 

CMYK color

 class.

set foreground color to {class:CMYK color, cyan:20.0,¬

magenta:90.0, yellow:50.0, black:50.0}
