the variation of either the focal length or the magnification of a lens system with different wavelengths of light, characterized by prismatic coloring at the edges of the optical image and color distortion within it.
However, avoid extensive use of pure red or blue text since they result in chromatic aberration and appear fuzzy.
Use of reflected branch avoids introducing chromatic aberration.
British Dictionary definitions for chromatic aberration
a defect in a lens system in which different wavelengths of light are focused at different distances because they are refracted through different angles. It produces a blurred image with coloured fringes
