Abstract
A method to display images using four or more different primaries having different spectral distributions wherein, in the LMS color space, at least two of these primaries have the same L coordinates and the same M coordinates; thank to the invention, different metamers, when being legally displayed, will be not only perceptually indistinguishable to a viewer with normal color vision but also indistinguishable by most of the viewers with non-normal color vision.
