Distance From OkZero

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):

1. W = L'*(M1*X).^(1/3)
2. 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.
