I have a new door that was installed a year ago. The frame is raw wood and I didn't paint it until recently. The wood is basically untreated. It hasn't been exposed to water much because it is under a shallow roof.
I primed it one time then painted it with a water based white paint the next day. As I was painting I noticed that there was a yellow tint on painted wood. (The paint is actually a year old too).
When the paint dried the yellowing was very noticeable.
Why did this happen? Was it the wood or the year old paint?
How do I rectify? I primed it again today and the yellowing is mostly gone. I can see a slight hint of it. I will probably prime another coat tomorrow.
Should I buy new white paint?
This is photo of the frame before priming and painting.
This is it after painting, discovering that it is yellowish and then priming again!
I can still tell that it is on the yellow side. You can see it compared to the white door.

I have seen primers allow wood tannins to bleed through, I use a schellac probably misspelled but standard primers being water based allows the oils in the wood to bleed through. I have used zinser and kilzs with success over wood and rooms that had smokers to stop the bleed through.
