C Specification

The possible color spaces are specified by the XrColorSpaceFB enumeration.

typedef enum XrColorSpaceFB {
    XR_COLOR_SPACE_UNMANAGED_FB = 0,
    XR_COLOR_SPACE_REC2020_FB = 1,
    XR_COLOR_SPACE_REC709_FB = 2,
    XR_COLOR_SPACE_RIFT_CV1_FB = 3,
    XR_COLOR_SPACE_RIFT_S_FB = 4,
    XR_COLOR_SPACE_QUEST_FB = 5,
    XR_COLOR_SPACE_P3_FB = 6,
    XR_COLOR_SPACE_ADOBE_RGB_FB = 7,
    XR_COLOR_SPACE_MAX_ENUM_FB = 0x7FFFFFFF
} XrColorSpaceFB;

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.
