Restricting the background color to an ovalbox

Question

The snippet

\documentclass[png,convert={density=600}]{standalone}
\usepackage{times,fancybox,varwidth,color}
\pagecolor{cyan}
\cornersize{1}

\begin{document}
\ovalbox{\large Hello}
\end{document}

generates the png image

with the help of pdflatex -shell-escape question.

How do I make the background fill just the ovalbox (while the ovalbox appears with no boundary)?

Answer 1

With tcolorbox?

Code:

\documentclass[png,convert={density=600}]{standalone}
\usepackage{times,tcolorbox}
\newtcbox{\myovalbox}{colback=cyan,boxrule=0pt,arc=5pt,
  boxsep=0pt,left=3pt,right=3pt,top=3pt,bottom=3pt}

\begin{document}
\myovalbox{\large Hello}
\end{document} 

Answer 2

Here is a tikz solution:

Code:

\documentclass[png,convert={density=600}]{standalone}
\usepackage{times}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
    \node [fill=cyan, rounded corners=5pt] {\large Hello};
\end{tikzpicture}
\end{document}
