The color values for the socks in the players.dbf are...
SOCKSSTYLE:
1:automatic invisible
2: ="= low
3: ="= middle
4: ="= high
5: ="= double high
6: BLACK invisible
7: ="= low
8: ="= middle
9: ="= high
10:="= double high
...and after it, the colored old school team socks come. Seems to be there are no ONLY white socks available by just editing socksstyle. I'm not sure but I think the sockscolor field is inactive for that... tryin' to find out anyways... will tell u later, got some ideas...
