Green cast when turning on the camera

Good day dear openmv forum,
I have a problem with my camera. I want to see the colors yellow, green and red. I start the program in front of a white wall. The problem is that after turning on the camera on the output image is a green cast. This means that I can no longer see the colors green and yellow very well. Is there perhaps a simple solution to the problem?

Yes, turn auto_white_balance() off immediantly on the start of your program.
