Target entity: CIE standard illuminants Context triple: [CIE Publication 15, defines, CIE standard illuminants]
-
A.
CIE daylight illuminants
CIE daylight illuminants are standardized spectral power distributions that model natural daylight for use in colorimetry and lighting design.
-
B.
CIE standard illuminant D65
CIE standard illuminant D65 is a standardized representation of average daylight with a correlated color temperature of about 6500 K, widely used as a reference white point in colorimetry and imaging systems.
-
C.
standard illuminant C
Standard illuminant C is a CIE-defined reference light source representing average daylight with a correlated color temperature of about 6774 K, used primarily for colorimetry and color matching applications.
-
D.
CIE standard illuminant A
CIE standard illuminant A is a standardized light source representing typical incandescent (tungsten-filament) illumination with a correlated color temperature of about 2856 K, used as a reference in colorimetry and lighting.
-
E.
CIE standard illuminant D50
CIE standard illuminant D50 is a standardized light source representing average midday daylight with a correlated color temperature of about 5000 K, commonly used as a reference for color-critical applications such as printing and graphic arts.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
