Been using all white or mostly white feathers (2 of 3) for over a decade, and have killed everything with them, from the ground and from the tree. I think the ability to see my arrows in flight, and at the point of impact, is much greater IMO than occasionally being "busted" by them. And I can't really say that I get busted any more than I usually would anyway. So there! :p
I started using them one year when I failed to see my arrow mortally hit a nice buck one evening in failing light, and hence, waited on bloodtrailing due to insufficient spoor. Next morning I found the deer in short order, but so had the coyotes. I had used a dark green stained shaft with grey barred feathers, and the dark colors got "lost" in the action. I've shot white ever since. Also, using white fletchings has made me a better shooter, as I can see my shots in my peripheral vision more clearly.
