I just downloaded the "ultimate_colour_palette.soc" from the 
"app.box.com" link.  Trying to view this 922.7 meg file crased "Kate" 
and another one.  The "default text viewer" took a few minutes to open.  
I did not finished the process, since it already went past more colors 
than I would want to use.

My "default" soc file was created for over 1,000 colors.  I am thinking 
to strip that creation to several others.  I have to go a long way to 
get to the Gold and Copper styles of colors.  The same for other groups 
of colors that might be easier than one large color file.

#######

The only issue[s] now is the fact that my HP Officejet 7000 [paper up to 
13x19 inches] has a different color printing than the Canon inkjets, 
with even differences within the Canon printers.  The MG5400 series - 
packed away as my spare printer - uses a different ink cartridges than 
my MG5320 and MG6220 ink set.  Both of the last two use the same ink so 
the color printed out on them look the same.

So, this means that if I print out a letter sized poster on the 
Officejet and the same file to the MG5400 series they look different 
with the Officejet a little darker.  The MG5320 and. MG6220 printers 
also look different from both the HP and the Canon 5400 series.

Note: since I packed it away, I do not remember if is a 5420 or 5440, 
etc. - I am reading the info from my "printer" option for Ubuntu/Mate 
laptop.  Also I have almost stopped using the MG6220 since it is making 
a lot of "noise".  The 5320 was a "replacement" for the noisy printer - 
which was my default printer.

[  I hope I am making any sense, since I have been up for almost 24 
hours now]
