All the sRGB colours in a Hilbert curve, sorted by their distance from {0,0,0} in Björn Ottosson's Oklab colourspace.
The (squares of the) distances were computed as (M-script based syntax):
- W = L'*(M1*X).^(1/3)
- for each column w in W: w'*w
where:
- X is a 3x16777216 matrix of sRGB colours converted to linear RGB,
- M1 as defined in Björn's programming sample in his blog post, and
- L is the Cholesky factorization of M2'*M2.
Generated as a farbfeld image with C++ and the Eigen library, then converted to PNG.
