Have you ever noticed what colour lightning usually has? I've found that it's usually neither yellow, nor blue...

I recently saw a bolt of lightning up close, like, from within 200 metres. It's definately blue, unless heavy rain or other effects can change that. The front window of my car is not tinted and it was at night, so naturally, i wasn't wearing sunnies.
Sort of off topic -> I was told a long time ago, that the difference in appearance between stars and planets (naked eye) is that stars 'twinkle' and planets do not. Is this true? Is the light reflected from planets not interfered with by atmospheric effects?
