A common RGB color space for digital movie projection from the American film industry.

DCI-P3 is a common RGB color space for digital movie projection from the American film industry.


Early history

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. The blue primary color is the same as sRGB and Adobe RGB; 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. 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.

  • In June 2017, Apple unveiled the second generation of the 12.9-inch iPad Pro and the new 10.5-inch iPad Pro, both shipped with a display supporting P3 color.
  • In June 2017, OnePlus 5 was released with this feature.
  • In September 2017, Apple unveiled the iPhone 8 and 8 Plus with support for P3 color. They also unveiled the iPhone X which also covers 100% of P3 color.
  • In October, 2017, Google released the Pixel 2, which covers 95% of the P3 color standard, and the Pixel 2 XL, which covers 100%.
  • In November 2017, HTC announced HTC U11+ phone with DCI-P3 color support.
  • In December 2017, Apple released iMac Pro, featuring P3 wide color.


  • In May, 2018, OnePlus launched the OnePlus 6 which also like its predecessor covers completely the DCI-P3 color space. Also Xiaomi Mi8 covers completely the DCI-P3 color space.
  • In October, 2018, Google released Pixel 3 and Pixel 3 XL which both cover 100% of the P3 color standard.


  • In January 2019, Asus launched the PQ22UC, a portable 21.6-inch 4K OLED screen with 99% DCI-P3 colour gamut that can run over USB-C.
  • In June 2019, Apple introduced the Pro Display XDR, a 32-inch 6K (6016 x 3384) screen with DCI-P3 10-bit color, 1,000,000:1 contrast ratio, and a wide viewing angle.
  • In November 2019 Acer released their new studio laptop series called "ConceptD"; one of its laptop ConceptD 3 and ConceptD 3 Pro has 15.6-inch DCI-P3 Full HD display.

System colorimetry

DCI-P3 uses a pure 2.6 gamma curve, a white luminance of 48 cd/m2, and a whitepoint with the same correlated daylight temperature as D63 but greener. Blue is the same as in BT.709.

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

Display P3

Display P3 is a color space created by Apple Inc. It uses the DCI-P3 primaries but with a D65 white point which is much more common among computer-display colorspaces (sRGB and AdobeRGB both use D65). Also unlike DCI-P3's 1/2.6 pure gamma curve, Display P3 uses the sRGB transfer curve (EOTF and thus display referred), which, for comparison purposes, could be approximated to a 1/2.2 gamma curve.

Display P3 (termed P3D65) is also used for some Netflix deliverables, including HDR and without BT.2020 container.
