# Original Image restored and a few small changes

I am new to LaTeX. I want to add a university logo below the first page (as shown in the photo below). Also, I want to change the color of box (I don't like the color red).

Tex file:

\documentclass[9pt,]{beamer}
\usetheme{Warsaw}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{dsfont}
\usepackage{color}
\usepackage{pifont}
\usepackage{tikz}
\usepackage{colortbl}
\usepackage{fancybox}
\setcounter{MaxMatrixCols}{50}
\usepackage{amsmath, amssymb, mathrsfs}
\usepackage{graphicx}
%\usecolortheme{beaver}
\definecolor{UBCblue}{rgb}{0.0, 0.5, 1.0}
\usecolortheme[named=UBCblue]{structure}
\setbeamercolor{block title}{use=structure,fg=white,bg=UBCblue!75!black}
\setbeamercolor{block body}{use=structure,fg=black,bg=white!20!white}
\title{Title}
\author{Name}
\institute{University}
\date{2020}
\begin{document}
\titlepage
\end{frame}
\begin{frame}
ABCDEFGH
\end{frame}
\end{document}


Result

Logo:

You can add your university logo at any field of the title page. In your case you want it below the date so you can change the \date command as follows:

\date{2020\par \includegraphics[width=0.2\linewidth]{JOoML.png}}


or even better (thanks to @Rmano comment)

\date[2020]{2020\par \includegraphics[width=0.2\linewidth]{JOoML.png}}


so you have the short date form 2020 if it is needed in the format elsewhere.

You can also add a small sized logo at each page of your presentation using

\logo{\includegraphics[width=0.5cm]{JOoML.png}} % optional


Changing the block color

You can change the color of any block by \setbeamercolor command then adding the name of the block and the color of your choice of the background and foreground. Here is an example you can use

\setbeamercolor{block title alerted}{bg=green!50,fg=black}


The output would be

\documentclass[9pt,]{beamer}
\usetheme{Warsaw}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{dsfont}
\usepackage{color}
\usepackage{pifont}
\usepackage{tikz}
\usepackage{colortbl}
\usepackage{fancybox}
\setcounter{MaxMatrixCols}{50}
\usepackage{amsmath, amssymb, mathrsfs}
\usepackage{graphicx}
%\usecolortheme{beaver}
\definecolor{UBCblue}{rgb}{0.0, 0.5, 1.0}
\usecolortheme[named=UBCblue]{structure}
\setbeamercolor{block title}{use=structure,fg=white,bg=UBCblue!75!black}
\setbeamercolor{block body}{use=structure,fg=black,bg=white!20!white}
\title{Title}

• +1, but it is better to use \date[2020]{2020\par \includegraphics[width=0.2\linewidth]{JOoML.png}} --- so you have the short date form if it is needed in the format. Jun 9 '20 at 15:31
• @Rmano Very nice remark. In fact I would have even inserted the logo in the \institute command and let the date be last. Will the short field form still apply. e.g. \institute[University ]{University \par \includegraphics[width=0.2\linewidth} ? Jun 9 '20 at 15:38
