[Bioc-devel] Build fail due to "undefined color `fgcolor`"

This seems to me like a change in the xcolor package, but I'm not sure. I opened an issue on the BiocStyle package at https://github.com/Bioconductor/BiocStyle/issues/109.

Dear Bioc Team,

I got today a build error from OUTRIDER and FRASER with:

LaTeX errors:
! Package xcolor Error: Undefined color `fgcolor'.

The same errror also pops up at other packages such as ggbio:

output file: ggbio.tex
! Package xcolor Error: Undefined color `fgcolor'.

I have the same error. I suppose there's an issue with BiocStyle.
After some debugging I found out that adding

\definecolor{fgcolor}{rgb}{0.345, 0.345, 0.345}
\newcommand{\hlsng}[1]{\textcolor[rgb]{0.192,0.494,0.8}{#1}}%
\newcommand{\hldef}[1]{\textcolor[rgb]{0.345,0.345,0.345}{#1}}%

right after the `BiocStyle::latex()` chunk fixes the issue.
