Hi, I have allways been a fan of oil based paints, but since the VOC changes of 2010 have noticed white paint going yellow after only a few months. I have done some researches and found this is now a common problem. In desperation I wondered if I could add a spot of blue paint to sort of create a blue whitener as is done with a blue rinse for net curtains. If so I wondered what ratio and what colour. If anyone has any idears or any other solutions it wold be appreciated. Thanks.
