Color of ball marker?

[farazzio]

can anyone please tell me what the different colors of the ball marker stand for... red yellowish green?.. does it help guess the swing and seam of the ball?

I think green means perfect line and length, yellowish ok line and length and red means bad line and length.

It does.

Dark red means it's usually going for six.
