Extended TAB function SYSCOLOR (63) allows you to change the Windows RGB value for certain parts of the Windows user interface. Note that this is offered on an as-is basis, and is not recommended due to:
| • | Conflicts between these settings and the current Theme |
| • | Conflicts with the "approved" way of changing Windows desktop settings (via the Control Panel) |
| • | Differences in the way it may work under different versions of Windows |
| • | Possible problems with the way other applications may respond to the fact of color changes (since any such change triggers a notification message to be sent to all affected applications). |
That said, if want to experiment with such changes, the syntax is:
? TAB(-10,AG_SYSCOLOR);id{,r,g,b};chr(127);
Where the id values are:

The RGB values r,g,b range from 0 to 255 (0,0,0=black; 255,255,255=white).
If you don't specify the r,g,b values, the TAB function will return a string in the keyboard buffer containing the current r,g,b values for the specified interface component.
Note that if you are associated A-Shell palette numbers with the standard Windows dialog background, window background, or text, you must do that first before using the TAB(-10,63) command.
