This is a follow-up to colorspace won't change colors in beamer where I'm getting issues with the colorspace package in beamer. Here's a MWE:


\definespotcolor{foo}{BarTone 555 GN}{.8,.2,.5,.3}

% Problem exists even without fix
% https://tex.stackexchange.com/questions/552478/colorspace-wont-change-colors-in-beamer
%\def\spc@getref#1 #2\@@{\def\spc@ir{#1}} %changed \gdef to def

    \draw[gr] (0,0) -- (10,0);

I get the following error (I'm only showing the part that seems to have info):

Runaway argument?
picture bounding box\endcsname {rectangle} \expandafter \edef \csname \ETC.
! File ended while scanning use of \spc@getref.
<inserted text> 
<*> tmp.tex
! Emergency stop.
<*> tmp.tex

I can't figure out what is happening. If I change foo to green for example, there is no error being generated. So it's only when I use a spotcolor that there is a problem.

I'm using the 2020 version of texlive and the latest 1.3 version of colorspace. Any thoughts?

    well it is not my fix, it fails without it too. but beside this it is quite a mess ;-(. – Ulrike Fischer Jul 6 at 18:55
  • Yeah, I should remove your fix because it still causes the same problem without it ._. It seems like a mess for some reason. The weird part is that it used to work in 2018. So something changed in the last couple years that made it stop working =/ – Aram Papazian Jul 7 at 3:00
  • It doesn't work in texlive 2018 for me. I get the error mentioned here tex.stackexchange.com/a/385570/2388. And with article it doesn't error but it doesn't give the correct color either. – Ulrike Fischer Jul 7 at 7:56

    It errors in 2017 and 2016 too. Also even if it not errorred, did it actually used spot colors? And why are you using spot colors for a presentation? – Ulrike Fischer Jul 7 at 12:07

    If you don't print the document spot color are useless. The pdf viewer will use the rgb/cmyk fallback. – Ulrike Fischer Jul 8 at 13:01
