How HEX becomes XYZ
Each step shows the values for the color above, as the converter computes them.
- Start Hex digits
#D3AF37 - Back 8-bit channels
each pair of digits read as a byte211 175 55 - Back sRGB channels, 0 to 1

About XYZ
CIE XYZ is the space every other one here is defined through: Y is luminance, and X and Z carry the rest of the color. CSS reads it as color(xyz-d65 …), with Y from 0 for black to 1 for white.
How this page writes it
- Linear sRGB is multiplied by the sRGB to XYZ matrix, built from the sRGB primaries and the D65 white.
- Written to five decimal places.
Watch for
- Some tools scale XYZ so that white has Y = 100; here and in CSS, white has Y = 1.
