Discussion
In a false - color set, human visual perception is limited to how many independent coordinates ?
Answer: A
Human colour vision is trichromatic: it is described by three independent coordinates, which can be the responses of the three cone types or hue, saturation and intensity. In a false colour set the image bands are assigned to the three display primaries, red, green and blue, so the observer can use only three independent coordinates. One, four or five coordinates do not describe human visual perception of colour.
