adding blocks in Presento beamer theme

Question

I wish to add blocks in Presento beamer theme. I am not able to get the frame around the blocks.

\documentclass[12pt]{beamer}
\usepackage{config/presento} 
\begin{document}
\begin{frame}
  \frametitle{Frame title}
  \begin{block}{Observation 1} 
    Simmons Hall is composed.
  \end{block}
  \begin{exampleblock}{Observation 2}
    Simmons Dormitory is composed of brick.
  \end{exampleblock}
  \begin{alertblock}{Conclusion}
    Simmons Hall $\not=$ Simmons Dormitory.
  \end{alertblock}
\end{frame}   
\end{document}    

How I would use the standard blocks in Presento beamer theme as in other themes like Madrid etc. What line should add/remove in the .sty file to get the frames around the standard blocks(like alert, example and basic block.) Thanks in advance.

Answer 1

The boxes are already there, but their colour is invisible. To make them visible, you can for example use \usecolortheme{orchid} to get the colours used in many of the standard themes.

% !TeX TS-program = xelatex

\documentclass[12pt]{beamer}
\usepackage{presento} 

\usecolortheme{orchid}

\begin{document}
\begin{frame}
\frametitle{Frame title}
\begin{block}{Observation 1} Simmons Hall is composed.
\end{block}
\begin{exampleblock}{Observation 2}
Simmons Dormitory is composed of brick.
\end{exampleblock}
\begin{alertblock}{Conclusion}
Simmons Hall $\not=$ Simmons Dormitory.
\end{alertblock}
\end{frame}   
\end{document}
