SuSE Linux: Versions up to (including) 7.3
You want YaST "in colors" ;-)
Start YaST with the parameter:
yast --plain
By doing this, the configuration file /var/lib/YaST/install.inf
is deleted and you can/must select all the YaST settings anew.
Alternatively, you can open /var/lib/YaST/install.inf with an editor
of your choice and set the value of "Monochrome" to 0 (zero).
Monochrome: 0
