How to change style and color of Table of Content?

Question

I want to change style and color of my Table of Contents to match this:

Note that I use the minitoc package for creating my Table of Contents on a per-chapter basis.

Answer 1

I don't know minitoc well, but here's a way to obtain the desired formatting for the partial ToCs using the titletoc package; once all the settings have been defined in the preamble, all the job is done using a single \PartialToC command:

\documentclass{book}
\usepackage{xcolor}
\usepackage{mdframed}
\usepackage{titletoc}

\definecolor{secnum}{RGB}{13,151,225}
\definecolor{ptcbackground}{RGB}{212,237,252}
\definecolor{ptctitle}{RGB}{0,177,235}

\titlecontents{lsection}
  [5.8em]{\sffamily}
  {\color{secnum}\contentslabel{2.3em}\normalcolor}{}
  {\titlerule*[1000pc]{.}\contentspage\\\hspace*{-5.8em}\vspace*{5pt}%
    \color{white}\rule{\dimexpr\textwidth-15.5pt\relax}{1pt}}

\newcommand\PartialToC{%
\startcontents[chapters]%
\begin{mdframed}[backgroundcolor=ptcbackground,hidealllines=true]
\printcontents[chapters]{l}{1}{\colorbox{ptctitle}{%
  \parbox[t]{\dimexpr\textwidth-2\fboxsep\relax}{%
    \strut\color{white}\bfseries\sffamily\makebox[5em]{%
      Chapter~\thechapter\hfill}Contents}}\vskip5pt}
\end{mdframed}%
}

\begin{document}

\tableofcontents
\chapter{Chapter One}
\PartialToC
\section{Section One One}
\section{Section One Two}
\section{Section One Three}
\section{Section One Four}

\chapter{Chapter Two}
\PartialToC
\section{Section Two One}
\section{Section Two Two}
\section{Section Three Three}

\end{document}

In a comment to the answer has been requested to produce a similar formatting for the general table of contents; in this case, some additional works has to be done:

\documentclass{book}
\usepackage{xcolor}
\usepackage{mdframed}
\usepackage{titletoc}
\usepackage{etoolbox}


\definecolor{secnum}{RGB}{13,151,225}
\definecolor{ptcbackground}{RGB}{212,237,252}
\definecolor{ptctitle}{RGB}{0,177,235}

\pretocmd{\tableofcontents}{\begin{mdframed}[backgroundcolor=ptcbackground,hidealllines=true]}{}{}
\apptocmd{\tableofcontents}{\end{mdframed}}{}{}
\patchcmd{\tableofcontents}{\contentsname}{\color{ptctitle}\contentsname}{}{}

\titlecontents{section}
  [4em]{\sffamily}
  {\color{secnum}\contentslabel{2.3em}\normalcolor}{}
  {\titlerule*[1000pc]{.}\contentspage\\\hspace*{-3em}\vspace*{2pt}%
    \color{white}\rule{\dimexpr\textwidth-20pt\relax}{1pt}}

\titlecontents{lsection}
  [5.8em]{\sffamily}
  {\color{secnum}\contentslabel{2.3em}\normalcolor}{}
  {\titlerule*[1000pc]{.}\contentspage\\\hspace*{-5.8em}\vspace*{2pt}%
    \color{white}\rule{\dimexpr\textwidth-15.5pt\relax}{1pt}}

\end{mdframed}%
}
