How To Correct White Balance?

[FidgetyRat]

I recently installed OpenIPC on a birdhouse camera (based on GK7605V100 sc2239) with no problems. It's up and running, but I cannot find any means of tweaking the white balance. Under the camera's original Chinese firmware, the image looks fine, but under OpenIPC, it's quite yellow/green (see images). The project overall seems really well done, but the documentation is simply just not there in most cases and I can't find any reference on how to tweak the image outside of setting the HUE/Sat/Lum settings in Majestic which won't affect my white balance issues.

Can anyone make a suggestion on what I need to fix?
