Plan OkA

All the sRGB colours in a Hilbert curve, sorted by their a component (green vs. red) in Björn Ottosson's Oklab colourspace.

The components were computed as (M-script syntax) W = M2(2,:)*(M1*X).^(1/3), where:

• X is a 3x16777216 matrix of sRGB colours converted to linear RGB,
• M1 and M2 as defined in Björn's programming sample in his blog post.

The blockiness near the zero point in the right middle is not computation error, I checked using ISymPy.

I will not upload one for the L (lightness) component, as it looks very similar to Distance From OkZero.
