spherochromatism

There is one form of spherical aberration that you may have seen if you’ve used very wide aperture lenses: spherochromatism. Like chromatic aberration, some lenses have corrected spherical aberration at some wavelengths better than others. This may result in a magenta tinge for out of focus areas in the foreground and a greenish tinge in the out of focus portion of the background (or vice-versa).
