Illuminants Chromaticity Coordinates

Defines CIE illuminants chromaticity coordinates for the CIE 1931 2 Degree Standard Observer and CIE 1964 10 Degree Standard Observer.

The following CIE illuminants are available:

  • CIE Standard Illuminant A
  • CIE Illuminant B
  • CIE Illuminant C
  • CIE Illuminant D Series (D50, D55, D60, D65, D75)
  • CIE Illuminant E
  • Illuminants F Series (F1, F10, F11, F12, F2, F3, F4, F5, F6, F7, F8, F9, FL3.1, FL3.10, FL3.11, FL3.12, FL3.13, FL3.14, FL3.15, FL3.2, FL3.3, FL3.4, FL3.5, FL3.6, FL3.7, FL3.8, FL3.9)
  • High Pressure Discharge Lamps (HP1, HP2, HP3, HP4, HP5)

The following other illuminants are available:

  • DCI-P3 (CIE 1931 2 Degree Standard Observer only) [2]
