I've seen many threads discussing cobalt blue lenses.  In the July 09 WJ suppliment, Sellstrom has an ad offering "Cobalt Blue" lenses, glasses, shields, etc.  Might be worth checking out.  It may also beat some of the ridiculously high prices I've seen asked for this stuff (here and other places as well). 

I don't weld anymore, but if anyone gets one of these I'd be interested to hear what they think.
