[Tex/LaTex] Unable to change the color of frame title

beamerformatting

This question is related to this post: Customization of the Copenhagen theme.

I am unable to change the color of the frame title to white.
I tried: \setbeamercolor*{frametitle}{fg=white}.

\documentclass[12pt]{beamer}
\usepackage[many]{tcolorbox}

 \setbeamercolor*{structure}{fg=myblue1,bg=blue}
 \setbeamercolor*{palette primary}{use=structure,fg=white,bg=structure.fg}
 \setbeamercolor*{palette secondary}{use=structure,fg=white,bg=structure.fg!75!black}
 \setbeamercolor*{palette tertiary}{use=structure,fg=white,bg=structure.fg!50!black}

\setbeamercolor*{item projected}{fg=red,bg=myblue3!80}

[Tex/LaTex] Change the background color in the title

It's quite unclear what you want to do; however this changes the background color of the title to green (pick your favorite color)

\newsavebox{\titlebox}
\pretitle{%
  \vspace{-30pt}
  \noindent\HorRule\\[1ex]
  \begin{lrbox}{\titlebox}
  \begin{minipage}{\dimexpr\textwidth-2\fboxsep\relax}\raggedright
  \fontsize{50}{50}\usefont{OT1}{phv}{b}{n}\color{DarkRed}\selectfont
}
\posttitle{%
  \par
  \end{minipage}\end{lrbox}
  \colorbox{green}{\usebox{\titlebox}}\par
  \vskip 1ex}
\title{This is the title of the template article}

The code should go in place of your original \pretitle and \posttitle definitions.

[Tex/LaTex] How to change default theme title style (bold, color, margin) of title in the beginning of each slide

One option would be to set the frametitle template to add the horizontal rule; something along these lines:

\documentclass{beamer}

\setbeamertemplate{frametitle}{\color{black}\bfseries\insertframetitle\par\vskip-6pt\hrulefill}

\begin{document}

\begin{frame}
\frametitle{Test title for the frame}
\end{frame}

\end{document}

enter image description here

To keep the exact formatting of the original frametitle template, you can change the default definition (I wasn't sure about the position of the rule in the case of a frame subtitle, so I opted for placing the rule below a possible frame subtitle; this can be easily modified):

\documentclass{beamer}

\makeatletter
\setbeamertemplate{frametitle}
{
  \ifbeamercolorempty[bg]{frametitle}{}{\nointerlineskip}%
  \@tempdima=\textwidth%
  \advance\@tempdima by\beamer@leftmargin%
  \advance\@tempdima by\beamer@rightmargin%
  \begin{beamercolorbox}[sep=0.3cm,left,wd=\the\@tempdima]{frametitle}
    \vbox{}\vskip-1ex%
    \if@tempswa\else\csname beamer@fteleft\endcsname\fi%
    {\strut\color{black}\bfseries\insertframetitle\strut\par%
    {%
      \ifx\insertframesubtitle\@empty%
      \else%
      {\usebeamerfont{framesubtitle}\usebeamercolor[fg]{framesubtitle}\insertframesubtitle\strut\par}%
      \fi
    }%
    \vskip-1.5ex%
    \rule{\dimexpr\paperwidth-0.6cm\relax}{0.4pt}}
    \if@tempswa\else\vskip-.3cm\fi% set inside beamercolorbox... evil here...
  \end{beamercolorbox}%
    %
}
\makeatother

\begin{document}

\begin{frame}
\frametitle{Test title for the frame}
\end{frame}

\end{document}
