I hit a box of yellows and didn't find any benefit in visibility, even worse when the leaves came down.
So still prefer white. The best way to not lose balls remains to just improve and be a better hitter........
Haven't tried orange yet, but that might do the trick. Though I'd hate to offend the traditionalists in their knickers tucked into their socks and sweater vests and ugly hats that came with a free bowl of soup.
I have a bag of very old golf balls (we had a ravine in the course I played at as a kid) - I hit a few into the woods when I'm bored. Most over 20-25 years old now. One that's still in there is a half yellow/half orange ball - call the "Eclipse". I don't even know who made those, but it was an interesting find back then.
edit: just did a search - they still make them. By "Nitro" (never heard of nitro)
that bag has balls with hexagonal dimples, the "Robinhood" ball (aka "Hot Ones" illegal balls), lots of old brands not in business anymore. And a lot of dried out crappy 'rocks' of course
