Changes

With {{cmd|startuseMPgraphic}}, you define a piece of graphics code that is processed anew every time the graphic is placed with {{cmd|useMPgraphic}}.

\def\mycolor{.625red}

For graphics that are the same every time, it is better to use {{cmd|startreuseableMPgraphic}}: the graphic is compiled only once, and the one resulting picture can be placed at various points with {{cmd|reuseMPgraphic}}.

\def\mycolor{.625red}

When reusing a graphic is not important, you can simply use {{cmd|startMPcode}}.

\startMPcode

fill fullcircle scaled 20pt withcolor .625green;
