# Change colors/contrast in beamer navigation between active and dimmed section

The code below gives the following output for the head:

Here the first section on the left is active and the others not, but the difference is quite small, I would like the active section to be in gray. Is there a way to control how the colors are mixed, so that I can increase the contrast (by dimming the inactive section even further)?

\documentclass{beamer}
\usetheme{Singapore}

\begin{document}
\section{one}
\begin{frame}
\end{frame}

\section{two}
\begin{frame}
\end{frame}

\section{three}
\begin{frame}
\end{frame}
\end{document}

You can use the apposite template section in head/foot shaded.

Example:

\documentclass{beamer}
\usetheme{Singapore}

\begin{document}
\section{one}
\begin{frame}
text
\end{frame}

\section{two}
\begin{frame}
text
\end{frame}

\section{three}
\begin{frame}
text
\end{frame}
\end{document}


With [10] it is defined the percentage of opaqueness.
