It looks like some kind of flare. Are you using anything else in the optical path, like a filter?

That color is the color you get with near-infrared light, and some lenses are just not designed to manipulate near-IR light correctly. In some outdoor situations, there can be more near-infrared light than usual, relative to visible light.
