Gradient filling with PSTricks

\documentclass{article}   
\usepackage{pst-grad,multido}   
\begin{document}

  \begin{pspicture}(-12ex,-3.5ex)(12ex,3.5ex)
  \pscustom[linestyle=none,fillstyle=gradient,gradangle=-90,
    gradbegin=orange!90!red,gradend=green!80!orange,
    gradmidpoint=0]{%
     \multido{\rA=-8+4}{5}{\pscircle(\rA ex,0){3ex}}}
  \rput(0,0){\large\textbf{Springboldene}}
  \end{pspicture}

\end{document}

and the same for a gradmidpoint=0.5

Here's how you can do it using TikZ: The filling will stretch over all circles as long as they're specified using a single \path (or \shade) command

\documentclass{article}

\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
\shade [left color=orange!90!red, right color=green!80!orange]
    \foreach \i in {-2,...,2}{
     (\i*3.5ex,0) circle [radius=2.5ex]
};
\node [font=\bfseries] (A) {Springboldene};
\end{tikzpicture}

\end{document}

My code seems to be verbose but the extra code is actually to get the precise dimension and placement. It also make you more convenient to adjust the parameters.

\documentclass[pstricks,border=0pt]{standalone}
\usepackage{multido}
\usepackage{pst-grad}
\usepackage[nomessages]{fp}


\newpsstyle{A}
{
    fillstyle=gradient,
    gradbegin=red,
    gradend=yellow,
    gradangle=30,
    gradmidpoint=0.5,
}

\psset{linestyle=none}


\def\greeting{Springboldene}
\def\hoffset{5pt}
\def\voffset{5pt}



\newsavebox\IBox
\savebox\IBox{\raisebox{\depth}{\greeting}}

\newlength\Left
\newlength\Right
\newlength\Top
\newlength\Bottom


\Left=\dimexpr-0.5\wd\IBox-\hoffset
\Right=\dimexpr0.5\wd\IBox+\hoffset
\Top=\dimexpr0.5\ht\IBox+\voffset
\Bottom=\dimexpr-0.5\ht\IBox-\voffset

% for circles
\FPset\a{-27.00}
\FPset\b{27.00}
\FPset\N{7}
\FPeval\step{round((b-a)/N:2)}
\FPeval\NplusOne{N+1}

\begin{document}
\begin{pspicture}(\Left,\Bottom)(\Right,\Top)
  \psclip{\pscustom{\multido{\nx=\a+\step}{\NplusOne}{\pscircle(\nx pt,0){8pt}}}}
      \psframe[style=A](\Left,\Bottom)(\Right,\Top) 
    \endpsclip
    \rput(0,0){\usebox\IBox}
  \end{pspicture}
\end{document}
