beamer add tag
I recently upgraded my version of texlive to

pdflatex --version
pdfTeX 3.141592653-2.6-1.40.22 (TeX Live 2022/dev/Debian)
kpathsea version 6.3.4/dev

Now when I try to render this skeleton beamer document:


\setbeamersize{text margin left=10mm,text margin right=5mm} 


\usetikzlibrary{tikzmark,shapes.geometric, patterns,decorations.pathreplacing, calligraphy}


\definecolor{titlecolor}{RGB}{29, 110, 174}

\newcommand{\tikzcircle}[3][red]{\tikz[baseline=-0.5ex]{\node[draw={#1}, fill={#1}, circle,text width=#2,minimum width=1.4em,text=black,align=center] at (0,0) {#3};}\hspace{0pt}}%




\begin{frame}[t, fragile]{\textsc{Morris} - Quality of estimate}




I get

! Package pgf Error: Unsupported color model `hsb'. Sorry.

How can this be fixed?

@Ulrike Fischer (as usual :)) nailed the problem. This was a temporary bug in beamer v3.65. You should update to beamer v3.66 or newer.

As a temporary workaround until you update, you could use
