Orange (colour) and political activities, with the colour orange being associated with Protestantism similar to the Netherlands. In optics, orange is the colour seen by the eye when looking at light with a wavelength between approximately 585–620 nm. It has a hue of 30° in HSV colour space. In the traditional colour wheel used by painters, orange is the range of colours between red and yellow, and painters can obtain orange simply by mixing red and yellow in various proportions; however these colours are never as vivid as a pure orange pigment. In the RGB colour model (the system used to create
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
