CIE 1931 xy Chromaticity – Rec. 2100 Chromaticities (Same as Rec. 2020)
BT.2100, more commonly known by the abbreviations Rec. 2100 or BT.2100, introduced high-dynamic-range television (HDR-TV) by recommending the use of the perceptual quantizer (PQ) or hybrid log–gamma (HLG) transfer functions instead of the traditional "gamma" previously used for SDR-TV. Rec. 2100 PQ specifically uses the perceptual quantizer.
The actual gamut of Rec. 2100 uses the same wide color gamut of Rec. 2020, but the color space itself supports an HDR range.

Input/Output
Parsed input and string output formats support all valid CSS forms:
color(rec2100-pq r g b / a) // Color function
When manually creating a color via raw data or specifying a color space as a parameter in a function, the color space name is always used:
Color("rec2100-pq", [0, 0, 0], 1)
The string representation of the color object and the default string output will be in the color(rec2100-pq r g b / a) form.
>>> Color("rec2100-pq", [0.53255, 0.32702, 0.22007], 1)
color(rec2100-pq 0.53255 0.32702 0.22007 / 1)
>>> Color("rec2100-pq", [0.55101, 0.49099, 0.30009], 1).to_string()
'color(rec2100-pq 0.55101 0.49099 0.30009)'
