The default is rather unfortunate here, and has to do with how KATE's 
highlighting works. Basically, it uses the system color for the 
background but its own presets for the various foregrounds... until you 
change them. However, everything is fully customizable; check in 
Settings->Configure Editor. My own KATE settings bear no relation to my 
system color settings. :-)

That sounds like a bug in Opera.

I doubt it. I know what a Qt palette looks like (from a programming 
standpoint); AFAIK KDE fills in everything. Most likely these issues are 
due to bugs in certain applications.

I agree. Unfortunately, far too many people do just this. :-(
