Just because it does and always has. I mean other colors work and work well, but that is the safest bet to catch crappie.
I use Silver/Blue/White a lot and it is very good and I just got the Silver UV stuff you see in my pic in my Sig and it worked well yesterday. I figured it would since I know Blue/White is so good.
I find most fish I try to catch like that color including Black Bass of all kinds.
