I can't verify the experience. But I suspect the blue stain is more often
called blue-green stain, and is caused by a fungus often spread by the bark

This is NOT NECESSARILY a bad thing. The wood used by Strativarius has
recently been tested and found to contain this same fungus. I wish I could
find the article now, but I'm pretty sure it appeared in McIlvainea.

Blue-green stained pine might have _quite_ a market among violin makers.
