Description

Enumerant Descriptions

  • XR_COLOR_SPACE_UNMANAGED_FB. No color correction, not recommended for production use.

  • XR_COLOR_SPACE_REC2020_FB. Standard Rec. 2020 chromacities with D65 white point.

  • XR_COLOR_SPACE_REC709_FB. Standard Rec. 709 chromaticities, similar to sRGB.

  • XR_COLOR_SPACE_RIFT_CV1_FB. Unique color space, between P3 and Adobe RGB using D75 white point. This is the preferred color space for standardized color across all Oculus HMDs.
