Best Answer

Per default beamer seems to use the colour part title for the boxes in the section and subsection pages. The following code redefines these pages with two independent colours, which can than be altered during the document to distinguish the individual sections. 

\documentclass{beamer}

\usepackage{beamerthemesplit}
\usetheme{PaloAlto}

\setbeamertemplate{navigation symbols}{}

\title[]{My Thesis}
\subtitle{}
\author[]{H. John}

\date{2016}

\listfiles

\setbeamercolor{author}{fg=blue}

\setbeamerfont{title}{size=\Large, series=\bfseries}
\setbeamerfont{author}{size=\footnotesize}
\setbeamerfont{date}{size=\small}

\setbeamertemplate{section page}
{
    \begingroup
    \begin{beamercolorbox}[sep=12pt,center]{section title}
        \usebeamerfont{section title}\insertsection\par
    \end{beamercolorbox}
    \endgroup
}

\setbeamertemplate{subsection page}
{
    \begingroup
    \begin{beamercolorbox}[sep=12pt,center]{section title}
        \usebeamerfont{section title}\insertsection\par
    \end{beamercolorbox}
    \vspace*{10pt}
    \begin{beamercolorbox}[sep=8pt,center]{subsection title}
        \usebeamerfont{subsection title}\insertsubsection\par
    \end{beamercolorbox}
    \endgroup
}


\begin{document}


    \begin{frame}
        \titlepage
    \end{frame} 

    \begin{frame}[t,allowframebreaks]
        \frametitle{Table of Contents}
        \tableofcontents
    \end{frame}

    \setbeamercolor{section title}{bg=cyan!50!black}
    \setbeamercolor{subsection title}{bg=cyan}

    \frame{\subsectionpage}

    \subsection
    [Lim]{Limits}
    \frame{\subsectionpage}

    \setbeamercolor{section title}{bg=green!50!black}
    \setbeamercolor{subsection title}{bg=green}

    \section

    \setbeamercolor{subsection title}{bg=yellow}

Remarks:

  • you do not need the package xcolor in beamer, beamer itself loads it.
  • instead of hacking the appearance like \author[]{{{\textcolor{blue}{\footnotesize H. John}}}}, beamer provides very comfortable mechanism to control font size etc. for its various components.
\setbeamercolor{author}{fg=blue}
\setbeamerfont{author}{size=\footnotesize}

EDIT: Meanwhile this problem was fixed in the Beamer development version (https://github.com/josephwright/beamer/commit/d05925d68cd467188096eb4f6b8f1993058c0641). It should be included in standard tex distributions starting with beamer v3.49.
