As Michael already reported, the match that had color problems was:

Falafel vs Mochy

Thanks, Michael.

In another post, I speculate that the bright teal (cyan or blue) board used in the Falafel-Mochy match may have been the problem. The auto-white balance fails when most of the frame has that color. Of course, manually setting white balance and color tint would correct it.

Alternatively, using a board with a neutral background, such as the one used in the match between Jeb Horton and Victor Ashkenazy, might also fix the problem. When the screen is mostly filled with a neutral gray, the auto-white balance can lock onto it. With such a board, it is not necessary to set white balance manually.
