On another forum a discussion of what deer see and UV light has been long going. I got me a UV light to check my clothing and found a few items do show a UV blue, but most did not. I happened to swing the light across my arrows, which are fletched with natural turkey and imitation barred feathers. I was surprised that any feather would show a UV bright appearance, but the imitation barred are very bright. The natural turkey are invisible and are beside the imitation. I also included a photo that shows the plastic nocks and plastic vanes showing UV brightness.
I would suspect several arrows with UV bright feathers would be visible in low light.
Just putting it out here for you to consider. Make your own choices.
