Keywords: CIExy1931 srgb gamut.png of the sRGB gamut The process of maximizing the value of R G or B results in a distinct 3-pointed star in the diagram centered at the D65 white point This is because although the chromaticities are correct the luminosities brightness values are not equal across the diagram If the luminosities were all made equal then the entire diagram would be rather dark since pure blue has a low luminosity Any attempt to equalize luminosity to remove the star will reduce the overall luminosity of the diagram and the star will not completely disappear until the diagram is very dark Alternatively we could blur the colors to get rid of the star which would give incorrect chromaticities I have opted for correct chromaticities at maximum brightness thus the presence of the star Transferred from http //en wikipedia org en wikipedia; transfer was stated to be made by User Aboalbiss 2006-05-06 Original uploader was Hankwang at http //en wikipedia org en wikipedia Released into the public domain by the author original upload log page en wikipedia CIExy1931_srgb_gamut png 2006-05-06 16 28 Hankwang 542×599× 106794 bytes <nowiki>Based on thumb CIExy1931</nowiki> en wikipedia Hankwang diagram Psychophysics Artificial intelligence Image processing CIE 1931 SRGB |
