Chromatic aberration(color fringing) is directly due to lens quality-especially at the long end of kit zooms-best way to cope with this phenomenon,is to not extend zoom to full capacity. Red,Green and Blue (primary colors) have differing wavelengths,and to avoid fringing we need to have all 3 colors converging on the one focal point.Proper way is to invest in very expensive glass, called "apochromatic lenses", where doublet correction elements are employed to counterract Chromatic Aberration. here's how ,(two ways) I control it in photoshop:
