Chapter and section name in footer beneath page number

Question

I would like to generate something like the pictures below. I already got the blue line and the numbering. Now i would like to also show the chapter name on the left pages, and the section name of the latest section on the right page.

I already tried to use \leftmark in the page numbering. But then it will be on the wrong side of the line.

How can i do this? Any hints are welcome :)

Thanks to all who will contribute :)

--- Edit

Here is the minimal code which shows, how i made the actual design:

\documentclass[twoside=true,a4paper,1.5pt,titlepage=on,]{scrreprt}

\usepackage{fancyhdr}
\usepackage{xcolor}
\definecolor{chaptercolor}{rgb}{0.36,0.73,0.82}

        {\color{chaptercolor}\rule[-90pt]{0.8mm}{100pt}}%
        \hspace*{10pt}\begin{minipage}[b]{1.5cm}%
            \color{chaptercolor}\normalsize\textbf{\thepage}%
        \end{minipage}%
    }
    \fancyfootoffset[EL]{1.85cm}
    \fancyfoot[EL]{%

        \begin{minipage}[b]{1.5cm}%

Note that it is not recommended to use fancyhdr together with a KOMA-Script class. So here is a suggestion using scrlayer-scrpage (part of the KOMA-Script bundle):

\documentclass[
  twoside=true,
  %a4paper,% default
  %%1.5pt,% unknown option!
  titlepage=on
]{scrreprt}
\usepackage{blindtext}% only for dummy text

\usepackage{xcolor}
\definecolor{chaptercolor}{rgb}{0.36,0.73,0.82}

\colorlet{ctcolorchapterline}{chaptercolor}
\colorlet{ctcolorchapternum}{chaptercolor}
\colorlet{ctcolorfooterline}{chaptercolor}
\colorlet{ctsectiontitles}{chaptercolor}
\colorlet{ctcolorfootertitle}{chaptercolor}
\colorlet{ctcolorfootermark}{black}


\usepackage[automark]{scrlayer-scrpage}% sets pagestyle scrheadings automatically
\clearpairofpagestyles
\lefoot*{\hspace{10pt}\leftmark}
\rofoot*{\rightbotmark\hspace{10pt}}
%\rofoot*{\ifstr{\rightmark}{}{\rightbotmark}{\rightmark}\hspace{10pt}}% alternative

\addtokomafont{pagefoot}{\normalfont\usekomafont{disposition}\color{ctcolorfootertitle}}
\renewcommand\chaptermarkformat{\textcolor{ctcolorfootermark}{\chapapp~\thechapter\autodot\enskip}}
\renewcommand\sectionmarkformat{\textcolor{ctcolorfootermark}{\thesection\autodot\enskip}}

\AddLayersToPageStyle{scrheadings}{pagenumber.odd,pagenumber.even}
\AddLayersToPageStyle{plain.scrheadings}{pagenumber.odd,pagenumber.even}
\DeclareNewLayer[
  foreground,
  oddpage,
  foot,
  contents={%
    \hfill
    \makebox[0pt][l]{%
      \pagenumberrule
      \hspace*{10pt}%
      \pagemark
    }%
  }
]{pagenumber.odd}
\DeclareNewLayer[
  clone=pagenumber.odd,
  evenpage,
  contents={%
    \makebox[0pt][r]{%
      \pagemark
      \hspace*{10pt}%
      \pagenumberrule
    }%
  }
]{pagenumber.even}
\newcommand*\pagenumberrule{%
  {\color{ctcolorfooterline}\rule[\dimexpr-10cm+\ht\strutbox\relax]{1.25pt}{10cm}}%
}
\addtokomafont{pagenumber}{\usekomafont{disposition}}

\begin{document}
\tableofcontents
\Blinddocument
\end{document}

Result:
