Facing colour according to the position that a particular regiment held in the order of battle - that is within a brigade, division or corps. As an example, amongst the Russian line infantry, the two brigades within each division were distinguished by red or blue shoulder straps; while the four regiments within each division wore red, blue, white or green collar patches and cap bands respectively. Facing colour A facing colour is a common tailoring technique for European military uniforms where the visible inside lining of a standard military jacket, coat or tunic is of a different colour to that of the
Colour recovery Combining the video-recorded colour signals with the monochrome telerecordings is a non-trivial task, requiring digital processing (for example matching up the different screen sizes of the two recordings). Thus, it wasn't until the early 1990s that cheaply available, sufficiently powerful computer hardware and software made this task particularly practical at that time. Black & white TV systems predate colour, and so subsequent analogue colour broadcast systems have been designed with backwards-compatibility in mind (known as a "compatible colour" system). Thus, the chrominance (colour) signal is typically 'shoe-horned' into the same channel as the luminance (brightness) signal, modulated on a fixed
