Usage examples
  • Colourless reflex reflectors must not produce a selective reflection; that is to say, the trichromatic coordinates "x" and "y" of the standard illuminant A used to illuminate the reflex reflector must not undergo a change of more than 0 701 after reflection by the reflex reflector. 3.1. This shall be verified by the visual comparison test indicated in 2.1 the control field being illuminated by a light source of which the trichromatic coordinates differ by 0 701 from that of standard illuminant A.

chromaticity coordinates
  • koordinaadid, mis määravad värvsuste geomeetrilised asukohad värvsusdiagrammil
  • ratio of the amount of one primary color to the total amount of all three necessary to reproduce a given color
värvsuskoordinaadid
Usage examples
  • Värvsus määratakse tavaliselt kahe tuletatud suurusega x ja y, kusjuures kolmest normaliseeritud väärtusest need kaks on kõigi kolme tristimuluse väärtuse funktsioonid (värvsuse koordinaadid) X, Y ja Z.

  • kolme värvikomponendi suhted kõigi värvikomponentide summasse
    Good to know
    • Kuna kõigi kolme värvsuskoordinaadi summa on 1, saab värvsust määratleda kahe värvsuskoordinaadiga.
    • CIE kolorimeetrilistes standardsüsteemides esitatakse värvsuskoordinaate tähistega x, y, z ja x 10 , y 10 , z 10 .
  • amounts of the three reference colour stimuli, in a given trichromatic system, required to match the colour of the stimulus considered
    Good to know
    • As the sum of the three chromaticity coordinates equals 1, two of them are sufficient to define a chromaticity.to entry:
    • In the CIE standard colorimetric systems, the chromaticity coordinates are presented by the symbols x, y, z and x 10 , y 10 , z 10 .
värvsuskoordinaadid
Usage examples
  • Värvsuskoordinaadid võimaldavad üheselt määrata kõik värvused.
