# Possible Beamer bug: Frame number has different color than date in infolines footer

I use TeX Live on Mac and I get my weekly updates through the TeX Live Utility. I am working on some slides for an upcoming talk. I am using the same Beamer templates and settings that I always use, so I was surprised to see that the page numbers that I always include at the bottom of my slides suddenly appeared in a different color. Here's an MWE:

\documentclass{beamer}
\useoutertheme{infolines}
\usecolortheme{beaver}
\title{Title}
\date{\today}
\begin{document}
\begin{frame}
\end{frame}
\end{document}


As you can see in the bottom right corner of the slide the page number appears but its color looks off. Until recently it would look exactly the same color as the date appearing next to it.

By Googling around a bit I managed to figure out how to get this to look normal again using the line commented out in the code above:

\setbeamercolor{page number in head/foot}{fg=darkred!60!black}


By uncommenting this line I got back the desired behavior:

So my question is not so much about how to fix this problem, but about why this is happening in the first place. Is this a bug that was introduced in a recent update, and if so will it be fixed? Is this a deliberate choice on the part of the developers (if so I can't imagine why)? Or am I doing something wrong or is something broken in my TeX setup?

I'd appreciate any insight on this. Thanks in advance!

Recently I introduced a new template (page number in head/foot) to make switching between different displays of page and frame numbers easier. Unfortunately this caused the previously unused colour to be used. Sorry for your problem!
