Is it possible to change the color of \alert command in beamer. See, it is not the alertblock!
For example, I would like to change to color yellow, because the standard color is red, and my background is dark blue.

Since (La)TeX doesn't have a “background color” for text, you would have to put your text inside a box which you can then color. Consider the following example using \colorbox.
\documentclass{beamer}
\setbeamercolor{alerted text}{fg=white,bg=red}
\newcommand{\boxalert}[1]{{%
\usebeamercolor{alerted text}\colorbox{bg}{\alert{#1}}%
}}
\begin{document}
\begin{frame}
Hello \boxalert{World}!
\end{frame}
\end{document}
Which renders
Edit: I'm no expert in beamer internals, so the following is nothing more than a hack. However, if you would like \boxalert to work with overlays, something like the following “seems” to work:
\newenvironment{boxalertenv}{\begin{altenv}%
{\usebeamertemplate{alerted text begin}\usebeamercolor[fg]{alerted text}\usebeamerfont{alerted text}\colorbox{bg}}
{\usebeamertemplate{alerted text end}}{\color{.}}{}}{\end{altenv}}
\newcommand<>{\boxalert}[1]{{%
\begin{boxalertenv}#2{#1}\end{boxalertenv}%
}}
...
Hello \boxalert<2>{World}!
After some digging, I located the definition of \alert in beamerbaselocalstructure.sty. The rest was easy. ;-)
EDIT: There's also a more "beamer-like" way. :-)
\documentclass{beamer}
% \renewcommand<>{\alert}[1]{\begin{alertenv}\bfseries#2#1\end{alertenv}}
\setbeamerfont{alerted text}{series=\bfseries}
\begin{document}
\begin{frame}
\alert{Some text.}
\end{frame}
\end{document}

I was think this command changed only alertblocks. I'm sorry by your time here. Thanks
