The dyes used in the digital camera sensors for capturing color are not very efficient so cross-channel color contamination is unavoidable and causes, for example, the chromatic aberration in the red channel to also be blended into the green channel along with any green chromatic aberration. It occurs because lenses have a different refractive index for different wavelengths of light (the dispersion of the lens). Whoever thought chromatic aberration was a good idea as a setting in games needs to be poisoned, scalped, cudgeled, sliced, flayed, bathed in lemon juice, shot out of a cannon, cut into tiny pieces, have the pieces burned to crispy bits and be buried next to Hitler.

This is a uniform problem across the frame, and is more of a problem in CCDs with a very small pixel pitch such as those used in compact cameras. ), Chromatic aberration also affects electron microscopy, although instead of different colors having different focal points, different electron energies may have different focal points.

The ambiguous acronym LCA is sometimes used for either longitudinal or lateral chromatic aberration.[2]. In optics, chromatic aberration (CA, also called achromatism or chromatic distortion) is a type of distortion in which there is a failure of a lens to focus all colors to the same convergence point.
