I use a green light & when I go to my stand I walk a creek bed to get there. Last week, I crested the creek bank and took two steps and looked to my right and saw a family of skunks within 10 ft of me. They never spooked (thank god for that, even though i wouldnt have to worry about applying anymore cover scents) & I was able to slide back into the creek and come up a little far down. So, I dont know ifgreen light wont spook deer but I know that it wont spook skunks.
