Color bleeding (image processing)

Example of color bleeding in the right half of the picture

The so-called color bleeding occurs with some video systems that do not separate the colors of the individual lines well from one another.

This effect occurs, for example, when copying several times on VHS , since color errors, in particular noise, are to be minimized here. In the picture on the right , the dark blue font Wikipedia shows clear bleeding on the right. Here, the brightness component of the picture is intact, but the color component literally "flows" downwards.
