What is the strange yellow discoloration on the walls of my house?

In several rooms in my house, there is an odd, faint yellowing in the corners of my walls near the ceilings. The walls and ceiling are painted white, and you can definitely see the yellow coming through. It's a relatively new house (built 2003) made of concrete block, with popcorn ceilings and orange-peel walls. We've lived there since the house was built, and the discoloration seems to be getting worse. No one has ever smoked in the house, and we don't have any fireplaces or anything like that. We do know that the builders used the "wrong tape" (whatever that means) in the ceiling in one room, which they came and fixed. There's no discoloration in the re-taped room. Does anyone have any ideas about what the discoloration is? Is it related to the tape, or is the tape just a red herring? Will just painting over it make it better?
