Customizing the RGB Database

The RGB database associates symbolic color names with specific Red, Green, and Blue (RGB) values. X applications request these values and/or color names when drawing on your screen.

To set the RGB Database:

  1. Select the Xconfig file in which you want to customize the RGB database and open the Exceed onDemand Xconfig dialog box.
  2. On the Video page, click Edit in the RGB Database area. The rgb.txt file opens in a text file editor.
  3. Make the necessary modifications to the rgb.txt file.

If you set new RGB values, they must be in the range of 0 to 255. The color name box is not case sensitive and spaces are ignored. Each valid line in the rgb.txt file has the following format:

Red

Green

Blue

Color Name

Sample:

70

130

180

SteelBlue

The color named SteelBlue has a Red value of 70, a Green value of 130, and a Blue value of 180.
Note: 
  The Exceed onDemand proxy log file contains a record of any client requests for colors not defined in the RGB Database. You can then add these colors to the database for future use.
  1. Click Save to save your changes and to close the text file editor.
  2. In the Exceed onDemand Xconfig dialog box, click OK to save changes and close the dialog box or click Apply and select another tab to continue modifying the Xconfig file.
