The CIE 1931 chromaticity diagram with the spectral colors and purple line along the rim. The corners of the triangle are the primary colors of the DCI-P3 color space. DCI-P3 D65 uses Illuminant D65 for the white point.

DCI-P3, or DCI/P3, is a common RGB color space for digital movie projection from the American film industry.[1]


Early history[edit]

In the CIE 1931 xy chromaticity diagram the DCI-P3 color space covers 45.5% of all chromaticities and 86.9% of Pointer’s gamut. In the CIE 1976 u’v’ chromaticity diagram the coverage is 41.7% and 85.5% respectively.[2] The blue primary color is the same as sRGB and Adobe RGB;[1] the red primary color is a monochromatic light source and has a wavelength of 615 nm. DCI-P3 was defined by the Digital Cinema Initiatives (DCI) organization and published by the Society of Motion Picture and Television Engineers (SMPTE) in SMPTE EG 432-1 and SMPTE RP 431-2.[3] As a step towards the implementation of the significantly wider Rec. 2020 it is expected to see adoption in television systems and in the home cinema domain.[4]

On November 10, 2010, SMPTE published SMPTE EG 432-1:2010.[5]

On April 6, 2011, SMPTE published SMPTE RP 431-2:2011.[6]

DCI-P3 uses a pure 2.6 gamma curve and a white luminance of 48 cd/m2.[5]

DCI-P3 has a 25% larger color gamut than sRGB.[26]
