[Tex/LaTex] Changing the background color in poster template

beamerpostertemplates

I am making a conference poster using a template provided in this link.

http://www.latextemplates.com/template/dreuw-deselaers-poster

I want to change the background color from gray to white and
also, I want to reduce the size of the header area ( Title area).
Please help me with this issue.

This is a summary of what already stated in the comments.

Block background color

It can be changed with \setbeamercolor*{block body}{bg=<color>,fg=black} directly in the provided .sty file

Title alignment

It can be changed by substituting

\usebeamercolor{title in headline}{\color{fg}\textbf{\LARGE{\inserttitle}}\\[1ex]}

with

{\centering\usebeamercolor{title in headline}{\color{fg}\textbf{\LARGE{\inserttitle}}\\[1ex]}\par}

in the .sty file.

This will center only the title, authors and institute will stay right aligned. If everything needs to be centered it is necessary to replace the first occourrence of \raggedright with \centering into \begin{beamercolorbox}[wd=\paperwidth]{headline} (again it can be done directly in the provided .sty file)

Based on your "half-way" solution, putting the logo column first moves the logo to the left side, like you wanted. Also, placing \vline inside the column environment eliminates the space before the line. It may not be elegant, but hopefully this is what you had in mind. Note that with this approach the height of the logo determines the height of the headline.

\documentclass{beamer}
\usepackage[size=a2, orientation=landscape]{beamerposter}
\usepackage{mwe}
\setbeamercolor{separation line}{bg=black}
\setbeamercolor{headline}{bg=white}
\setbeamercolor*{example header}{fg=black}

% ----------- Global Background -------------
\usebackgroundtemplate{%
    \includegraphics[width=\paperwidth,height=\paperheight]{example-image}%
}

% ----------------- Headline ------------------
\setbeamertemplate{headline}{%
\begin{columns}
\begin{column}{0.2\paperwidth}
\begin{beamercolorbox}[wd=0.99\linewidth]{headline}
    \vfill
    \centering
    \includegraphics[height=9cm]{example-image-golden-upright}
    \vfill
    \end{beamercolorbox}
\vline
\end{column}%

\begin{column}{0.6\textwidth}
\begin{beamercolorbox}[wd=.6\paperwidth]{example header}
    \centering
    \usebeamercolor{title in headline}{\color{fg}\textbf{\Huge{\inserttitle}\\[1ex]}}
    \usebeamercolor{author in headline}{\color{fg}{\huge{\insertauthor}\\[1ex]}}
    \usebeamercolor{institute in headline}{\color{fg}{\LARGE{\insertinstitute}\\[1ex]}}
\end{beamercolorbox}
\end{column}

\begin{column}{0.2\textwidth}
\begin{beamercolorbox}[wd=0.2\paperwidth]{example header}
\end{beamercolorbox}
\end{column}
\end{columns}

\begin{beamercolorbox}[wd=\paperwidth]{lower separation line head}
    \rule{0pt}{2pt}
\end{beamercolorbox}
}
\title{Title}
\author{Author}
\institute{Institute}

\begin{document}
This is some text.

[Tex/LaTex] Changing the header and footer and title images in a Beamer template

This is what I use, I have a custom user template for company colors for the titles blocks...

in preamble

    \defbeamertemplate*{title page}{customized}[1][]
    {
    \begin{flushright}
    \usebeamercolor{structure}
    \usebeamerfont{title}\inserttitle\par
    \usebeamerfont{subtitle}\usebeamercolor{subtitle}\insertsubtitle\par
    \bigskip
    \usebeamerfont{author}\insertauthor\par
    \usebeamerfont{institute}\insertinstitute\par
    \usebeamerfont{date}\insertdate\par
    \end{flushright}
    }

\title[]{yourtitle}
\subtitle[]{Subtitle}
\author[] {you}
\institute[] {company}
\date[] {tody is \today}
\subject{Subject of presentation}

Here you define the backgroud of the slides, I use only a custom footer of page width

\usebackgroundtemplate%
{%
\vbox to \paperheight{
\vfill
\includegraphics[width=\paperwidth]{slide} %your picture
    }%
}

And first slide

%--- the titlepage frame -------------------------%
{\usebackgroundtemplate%
{%
\includegraphics[width=\paperwidth,height=\paperheight]
{yourpicture}
\begin{frame}[plain]
\titlepage
\end{frame}
}
