Evolution of human colour vision that are found between 450 and 625. Individuals with various forms of colour blindness such as deuteranopia and protanopia are missing human middle wavelength sensitive or long wavelength sensitive opsins. Their minimum wavelength differences are <5 but only at around 500. Protanopes, who are missing long wavelength sensitive cones, are unable to distinguish between colours in the green-yellow-red section of the electromagnetic spectrum. They find yellow, red and orange colours to have much lower brightness when compared to a trichromat. The dimming of these colours can result in confusion in many cases, such as when attempting to identify red traffic
Colour recovery the broadcast and release of colour-recovered episodes of "Dad's Army" and "Doctor Who". "Example of the chroma dot reconstruction:" Colour recovery Colour recovery (or colour restoration) is a process which can restore lost colour, specifically to television programmes which were originally transmitted from colour video tape, but for which only black & white copies remain archived. Not to be confused with colourisation, colour recovery is a newer process and is fundamentally different from colourisation for several reasons. Firstly, colour recovery can only be performed if the originally transmitted colour signal can be reconstructed or recovered from some source, whereas this
