Two of the primaries G1', G2' are distributed in the green part of the visible spectrum, one G1' mainly distributed between 500 and 540 nm, the other one G2' mainly distributed between 540 nm and 585 nm. Thank to the specific spectral definition of the primaries B', G1', G2', R1' and R2', colors can be easily displayed that are metameric for most of the viewers, allowing notably anti-camcorder defeat in movie theatres without prejudice for the quality of display for most of the viewers.
