Fir Tree With Purple Cones On Twin Lakes

Up in Twin Lakes, there is a row of fir trees in the side/rear yard close to the property line.  Well...at least I *think* they're fir trees.  I'm no conifer expert, so they might be spruce trees?  Chime in here if you know for sure.  Anyway...they were there when we arrived and they provide a good amount of screening.  And I never thought about them too much until I was recently walking by them as I dragged a tube from the garage to the pier and notice something pretty incredible about them:  They have purple cones.  

They're pretty tightly wound up cones, but they're definitely purple.  A little bit of searching says that they might be Picea purpurea or they might be Korean Fir - Abies koreana.  Either way, they're pretty great to look at up there right now.  I'll keep an eye on the cones to see if they turn from purple to brown as they dry out and drop.
