[Tex/LaTex] Creating a document with no borders or margins

geometrymarginsminipage

I want to create a small flyer. It should be folded once and have four pages in total. Also, I need a special geometry.

So far, I am trying to achieve that using minipages. Here is my MWE:

\documentclass{article}

\usepackage[landscape, paperwidth=15cm, paperheight=30cm, left=0mm, top=0mm, bottom=0mm, right=0mm, margin=0mm]{geometry}
\usepackage{xcolor}

\setlength{\fboxsep}{0pt}
\setlength{\parindent}{0pt}

\begin{document}
    \pagestyle{empty}%
    \colorbox{blue!50}{\begin{minipage}[t][\paperheight][t]{0.5\paperwidth}
        FRONT COVER
    \end{minipage}}%
    \colorbox{green!50}{\begin{minipage}[t][\paperheight][t]{0.5\paperwidth}
        BACK COVER
    \end{minipage}}%
    \clearpage
    \colorbox{red!50}{\begin{minipage}[t][\paperheight][t]{0.489\paperwidth}
        INSIDE LEFT
    \end{minipage}}%
    \colorbox{black!50}{\begin{minipage}[t][\paperheight][t]{0.489\paperwidth}
        INSIDE RIGHT
    \end{minipage}}

\end{document}

Now I have several problems with that.

  1. The color boxes do not align with the page borders. Instead, there is a small white margin above of the color boxes.
  2. On the first page (front/back cover), these white margins are not even of the same size.
  3. On the second page (inside left/right), the boxes do not align with the right page border, either.

Clearly, using minipages is either not the right way to create such a flyer, or I misunderstood how this should be working (or both). It is important that everything aligns well for the later folding. Any help is appreciated.

Here is one try with tabulars.

\documentclass{article}

\usepackage[landscape, paperwidth=15cm, paperheight=30cm, margin=0mm]{geometry}
\usepackage[table]{xcolor}

\begin{document}
    \pagestyle{empty}%
    \noindent
    \begin{tabular}{@{}c@{}}
    \cellcolor{blue!50}%
    \begin{minipage}[t][\paperheight][t]{0.5\paperwidth}%
        FRONT COVER
    \end{minipage}%
    \end{tabular}%
    \begin{tabular}{@{}c@{}}
    \cellcolor{green!50}%
    \begin{minipage}[t][\paperheight][t]{0.5\paperwidth}%
        BACK COVER
    \end{minipage}%
    \end{tabular}%
    \clearpage
    \noindent
    \begin{tabular}{@{}l@{}}
    \cellcolor{red!50}%
    \begin{minipage}[t][\paperheight][t]{0.5\paperwidth}%
        INSIDE LEFT
    \end{minipage}%
    \end{tabular}%
    \begin{tabular}{@{}l@{}}
    \cellcolor{black!50}%
    \begin{minipage}[t][\paperheight][t]{0.5\paperwidth}%
       INSIDE RIGHT
    \end{minipage}%
    \end{tabular}%
\end{document}
