I recall there was an issue with white balance on the GX10 that was fixed with firmware update 184.108.40.206:
"Changes in Firmware Version 220.127.116.11:
1. Fixes a white balance error that may occur when using Auto mode or a Special Scene mode* depending on usage conditions.
* Portrait/Sports/Night Scene/Snow/Low Light/Spotlight"
Could that be your issue ?
