How to use the PANTONE color (SPOT color) in LaTeX2e? Is there any package available?
As far as I can see, the »xspotcolor« project hasn't been updated since 2013 and I fail to find the package on ctan. However, it consists of a couple of files and adding the code of xspotcolor.sty would not suffice.
But Javier Bezos has written the colorspace package, which also allows using pantone spotcolors. See here: Package colorspace, updated in October 2016! It supports pdftex, but not, as far as I understand the manual, compiling with LaTeX to a DVI.
If you can live with pdfTeX, this seems the way to go.
Take a look at
xespotcolor by Apostolos Syropoulos. It works well with XeLaTeX and TikZ and it did a great job for me.
