Deer notice movement more than they do color anyhow.
That sure is true. I had a doe look straight at me for 30 seconds then keep going. The cool part is that I was 8 years old, wearing the hugest brightest flo orange coat with and yellow hat (i'm sure my cheeks were really red too). She looked and I didn't blink. so, I don't worry too much about my fletchings up in the tree.
