Which color space is associated with HDR content?

• A. Rec.2020 defines the color space for HDR.
• B. Rec.709 defines the color space for HDR.
• C. DCI-P3 defines the color space for HDR.
• D. sRGB defines the color space for HDR.

Answer: (A)

HDR relies on a wider color gamut to match the higher contrast and brightness, giving richer and more varied colors. The color space associated with HDR content is Rec.2020, which covers a much larger portion of the visible spectrum than older standards. This broader gamut, along with high bit depth, lets HDR formats like HDR10 deliver more saturated and nuanced colors. In contrast, Rec.709 is the SDR standard with a smaller gamut, DCI-P3 is a cinema-wide gamut used in some contexts but not the general HDR standard, and sRGB is a smaller color space geared toward web and graphics rather than HDR. So Rec.2020 is the color space most closely linked to HDR content.
