Cross-luminance

Chroma crawl
An artifact that occurs when the brightness information from the luma channel is incorrectly interpreted and applied to the YUV color space.

In television technology, cross-luminance is an undesirable effect that occurs when the brightness information from the luma channel is incorrectly interpreted and applied to the YUV color space. It results in a crawling dot pattern seen on the edges of saturated colored objects. The cross-luminance artifact is most visible along the sharp or moving edges of objects with colored edges; it looks like parasitic dots.
