Color Space Conversions
Input: opaque 8-bit sRGB; CIE 1931 2° observer. XYZ and CIELab/LCh use D65 unless marked D50; D50 conversions use Bradford adaptation. XYZ white is Y = 100, or Y = 1 for CSS and u′v′Y. Displayed coordinates are rounded.
Match distances use ΔE′ CAM16-UCS: lower values mean closer digital swatches. These values are not interchangeable with CIE76 or CIEDE2000 and do not guarantee a physical paint match.
Y′CbCr values are normalized coordinates or unquantized 10-bit limited-range code values.
CIECAM02 and CAM02-UCS: D65; LA = 40 cd/m²; Yb = 20 (Yw = 100); F = 1, c = 0.69, Nc = 1.
CAM16 and CAM16-UCS: D65; LA = 40 cd/m²; Yb = 20 (Yw = 100); average surround (F = 1, c = 0.69, Nc = 1).
HCT (Material Color Utilities): D65; LA ≈ 11.73 cd/m²; Yb = 18.42 (Yw = 100); F = 1, c = 0.69, Nc = 1; T = L*.
JzAzBz and JzCzHz use white at 1 cd/m². This luminance convention is separate from the BT.2100 preset.
ACES values use a colorimetric conversion with Bradford adaptation; they do not reconstruct scene exposure.
BT.2100 PQ/HLG and ICtCp assume sRGB white at 203 cd/m². HLG: peak 1000 cd/m², black 0 cd/m², system gamma 1.2, reference surround.
