Colour-sided Colour-sided Colour-sided is a colour pattern of domesticated cattle. It is sometimes called lineback It consists of a dark body colour, with white finching along the spine, white under the belly, and often white also over the tail, head and legs. The ears, nose and feet are generally dark. The pattern may occur in many breeds, but some breeds are consistently colour-sided, including English Longhorn cattle, Irish Moiled cattle, Randall cattle, Riggit Galloway cattle and Lineback cattle. The dark colour may be any solid colour such as black, red or brindle. An extreme pale form of the colour-sided pattern is
Colour recovery to remove this interference, these patterns are retained even in the existing monochrome film prints and theoretically contain the original colour information. (Occasionally the colour information was filtered out using a notch filter and is lost.) The idea to recover this information was originally suggested by BBC researcher James Insell. In practice however, the recovery of this colour information from telerecordings is highly complex for several reasons. Firstly, the colour reference timing signal, known as the "colour burst," is absent from telerecordings, as it is nominally off the edge of the visible screen area being recorded. This timing has to
