¿Cómo disminuir el espacio vertical del entorno sombreado (\usepackage{framed})?

Question

¿Cómo disminuir el espacio vertical del shadedentorno en el preámbulo? Aquí está el código:

\documentclass[a4paper,12pt]{article}
\usepackage{color,xcolor}
\usepackage{framed}
\colorlet{shadecolor}{blue!11}

\begin{document}
text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text 
\begin{shaded}
text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text
\end{shaded}
text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text

text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text
\end{document} 

No defina el nuevo entorno, simplemente cambie algunas propiedades del shadedentorno.

Fuera de tema: No cargar colorpero solo los más modernos xcolor.

Puede redefinir el espacio vertical redefiniendo la framedlongitud interna OuterFrameSep:

\documentclass[a4paper,12pt]{article}
\usepackage{xcolor}
\usepackage{framed}
\colorlet{shadecolor}{blue!11}
\setlength{\OuterFrameSep}{0pt}

\begin{document}
    text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text 
    \begin{shaded}
        text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text
    \end{shaded}
