Creates the database used by the X-Window system server for colors.
rgb [ DatabaseName ] [ <InputfileName ]
The rgb command reads lines from standard input and inserts them into its database to associate color names with specific red, green, and blue (RGB) values.
The rgb command produces two output files: DatabaseName.dir and DatabaseName.pag. If you do not specify a database file name, the default names rgb.dir and rgb.pag are used.
Each color entry is in the form:
Red Green Blue Colorname
where the Red, Green, and Blue elements are integer values ranging from 0-255. The actual color is determined by how the elements are combined. Each element can range from no intensity (0) to full intensity (255). The Colorname parameter can be descriptive or fanciful. For example, the sequence 250 250 250 could be named white or snow. Two or more entries can share the same element numbers or names.
| DatabaseName | Specifies the database to create for the output data. |
| <InputFileName | Specifies the name of the input file. |
