You can modify the colours like this:

\documentclass{beamer}
\usetheme{Antibes}

\setbeamercolor{palette primary}{bg=red!80!black}
\setbeamercolor{palette secondary}{bg=red!70!black}
\setbeamercolor{palette tertiary}{bg=red!60!black}
\setbeamercolor{palette quaternary}{bg=red!50!black}

\setbeamercolor{background canvas}{bg=gray!50!white}

\begin{document}
    \begin{frame}
        \frametitle{test}
        test
    \end{frame}
\end{document}
