Graphics, Figures & Tables ⇒ Colored Box with rounded Corners around Figure

[onako]

For my work, I'supposed to present some figures which need to be surrounded with a _thin_colored_box with rounded corners_.
I read there are ways to achieve this with text, but I wonder how to achieve this with a figure. Simple

Code: Select all

\usepackage{float}
\floatstyle{boxed} 
\restylefloat{figure}

would put a black box around figures. Any suggestions?
