I use red Nockturnals and they are pretty bright. I put some CX green lighted nocks on my nephews arrows and the green was a little easier to see if it was bright out. But I wanted the nocks for lower light conditions and seeing where my arrows hit (like first light shots) so it was a non-issue for me.
Really dont matter what color just whatever one you like lol i used green and had no problems with it just never got to use it cuz i bought new arrows and it didnt fit the new arrows i got.
I use the red nockturnals and there bright i even shoot them in the dead of night for yotes they work great.
I think I'm going to try blue, I've never seen anything blue in the woods so they should stick out pretty well Sent from my iPhone using Tapatalk
In use Red and Green and they both are very bright. I don't think you will be disappointed with any color you choose.
Scientifically speaking, human eyes see green better than red. That's why green laser is so controversial.
I used red CX nocks for 2 years. Then tried the green. They were a little easier to see. This year I switched to blue nockturnals. Can't really see them in bright light, but they really stand out in low light conditions
I use blue - I feel they stand out the best in daylight conditions - they are all easy to see in low light.
