If you are referring to purple/blue fringe, it's called chromic aberration and it's more evident is some lenses than others. It occurs when you have a very contrasty picture, i.e., a lot of black next to white. Almost all of it can be removed by some of the post processing programs, either directly, or simply by reducing the blue and red channels. This shot has a contrast range way beyond a camera's abilities to capture. You may be able to get both the barn interior and the outside exposed correctly useing HDR, or some post processing methods.

Thank you. This is very helpful. I'll adjust the chromic aberration setting in LR.

adj.
1.
a. Relating to colors or color.
b. Relating to color perceived to have a saturation greater than zero.
