Colors can be created and manipulated as objects in GISDK using the functions shown below:

GISDK Function	Summary
ChooseColor()	Gets a color using the Windows Color dialog box
ColorCIE()	Creates a color based on its (x, y, g) coordinates in the CIE chromaticity space
ColorHLS()	Creates a color based on hue, lightness and saturation
ColorHSV()	Creates a color based on hue, saturation and value (brightness)
ColorRGB()	Creates a color based on the amounts of red, green and blue
GeneratePalette()	Generates an array of gradually changing colors
GetColorCIE()	Returns the (x, y, g) coordinates of a color in CIE chromaticity space
GetColorHLS()	Returns the hue lightness and saturation of a color
GetColorHSV()	Returns the hue, saturation and value (brightness) of a color

As a convenience, there is a shared options array cc_Colors that contains twelve standard colors:

For example, the following will use ColorRGB(65535, 65535, 0) as the icon color:

...

SetIconColor(, cc_Colors.Yellow)

You can get and set the red, green, blue, and alpha (opacity) properties of a color with selectors; for more information, see Compound Variables.
