[Rivet] Line Colors

[Hendrik Hoeth]

Hi,

FYI: the problem here was indeed the ancient LaTeX version that comes
with the ancient SL4 (e.g. on lxplus!). It wasn't the first time that
we've seen that issue, so now we provide a couple of up-to-date files
in $PREFIX/share/Rivet/texmf/ and set the HOMETEXMF path to that
directory. With this make-plots works fine on SL4 now and we can use
any color scheme we want. Probably we want to change this back once SL4
has died, i.e. in 10 years or so.

Cheers,

   Hendrik
