Hi,

2 way to correct this,

Grinner has the right answer and cost nothing except read the manual on white balance plus experiment.

The other solution need info about light used to yhe game field, if they use only one kind of light you can find a filter to correct the situation if they use mixed light system with mercury and other system like sodium if very difficult to find a filter or filters to work. Normally mixing light systems get in trouble.
