Grey out individual bullet points

Question

I know how to grey out points so it greys out all except one bullet point and then keep going to other bullet points. But that isn't what I want.

What I want is for the bullet point to never be black, so that there is only a single great bullet point. For example:

\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}
\item This is gray
\item This is gray
\item This is black
\end{itemize}
\end{frame}
\end{document}

In other words, I want only this slide to display:

There should be no slides before or after this.

Answer 1

You can use <0> (together with \setbeamercovered{transparent} as in this answer).

\documentclass{beamer}
\setbeamercovered{transparent}
\begin{document}
\begin{frame}
\begin{itemize}
\item<0> This is gray
\item<0> This is gray
\item This is black
\end{itemize}
\end{frame}
\end{document}
