Lenses ideally project the color spectrum right on the sensor, creating a sharp image. But in reality, there are several colors in the spectrum that aren’t precisely projected, especially in low quality lenses. In cases like these, the focus falls outside the intended focus point, sometimes in front and sometimes behind the sensor. This means that it spreads or disperses (not focused on one point). Because it doesn’t fall on one exact point, chromatic aberration is resulted in the photographs produced. Characteristics of a chromatic aberration is the visibility of odd colors on the edges of the objects in the photo, usually in the color of purple, blue, green, or red.
High quality lenses (like Canon’s L Series or Nikon’s ED Lenses) uses optic materials that have super low dispersion, minimizing the spreading of colors.
