This is a logical progression and well received, congratulations!  

So LibreOffice now needs to verify our sRGB .soc palette to matches the sRGB
values for the HLC/CIE Lab colors submitted to DIN.

As noted in our BZ tdf#104052 when we implemented an HLC color palette, the
dtpStudio prepared PDF color fan had listed sRGB values for each HLC color
could differ considerably from the sRGB color values of   freecolour-hlc.soc
we distribute.

Not wrong (the CIELAB color conversion to sRGB depends on algorithm
used--adobe CMS vs little-CMS2 and ICC profile) but we need to assure that
our published .soc file matches what has been submitted to DIN.  

Would you please post the sRGB listing of the DIN submission to the TDF BZ
issue [1]?
