    "abstract": "Video processing is generally concerned with colour represented in three components derived from the scene, usually red, green and blue or components computed from these. But accurate colour reproduction depends on knowledge of exactly how the physical spectra of the original scene are transformed into these components, and exactly how the colour components are transformed to physical spectra at the display. These issues are the subject of this article.",
