Don't.

Lightning bolts are exactly /how/ hot? Some 20-30 kK, right? Color 
temperature (i.e. the visible portion of the corresponding blackbody 
radiation) doesn't get any more blue than that. And with the air being 
turned into a plasma, emission from electron energy state changes within 
individual atoms plays only a minor role compared to the thermal 
emissions from free electrons and ions.
