)

'Usage
 
Dim instance As IThemeColor

void SetColorRGB( 
   int color,
   int red,
   int green,
   int blue
)

Parameters

color: The integer value (between 0 and 15) that you want to change the mapping for in the color map. See the Remarks for more about how colors are mapped.
red: An integer value that specifies the degree of red saturation (red RGB value) for the new color. This can be any value between 0 and 255.
green: An integer value that specifies the degree of green saturation (green RGB value) for the new color. This can be any value between 0 and 255.
blue: An integer value that specifies the degree of blue saturation (blue RGB value) for the new color. This can be any value between 0 and 255.

In Open Systems sessions, screen colors are mapped to integer values in a color map. Although you can select from only one of 16 colors, you can change the actual screen colors to any RGB values by changing the RGB values of the color map.

For example, if the screen foreground color of normal text is mapped to 0 in the map (which has a default color of Black), you can change the default RGB value mapped to 0 to another RGB value.

You can use this approach to change the actual screen foreground or background color to any RGB color. Use the GetBackgroundColorAsInt Method or GetForegroundColorAsInt Method methods to get the integer value that is mapped to the screen color and then use this method to change the mapping for that color to any RGB value.

You can view the theme color map in the user interface by clicking Color Map, under Text Color Mapping in the Modify Theme dialog box.

The default color mapped to each integer value is shown below.
