I do have a couple of whiteblueish trees among green regular pine trees near Whiterun stables. Are they sopposed to be intentional? Or is it kind of a mod problem/conflict? The latter seems likelier to me. Looks unnatural somehow.
Mods that might have caused it, though I'm not sure:

Lush Trees
Skyrim Flora Overhaul
Serious Skyrim HD

Any ideas or help is truly appreciated. Thank you!

Probably from the overhaul and Lush trees conflicting...or due to the overhaul having missing textures.
