Hi Hans,

this is what I was looking for, I adapted now my example and it works fine.

The next thing is to change the macro for my own needs but I can do
this later when I will integrate it into my macro, I wanted to know at the
moment of I can use layers as a replacement for fieldstacks and the
solution was yes.

\usemodule[pre-60]

\setupcolors[state=start]
\setupinteraction[state=start,click=off]

\setupbackgrounds[text][background=]

\starttext

\StartLocalSteps

\framed
  [width=2cm,
   height=2cm,
   offset=overlay,
   background=invoke]
  {\dorecurse{4}
     {\StartLocalStep
      \ifcase\recurselevel\or\red\or\green\or\blue\or\yellow\fi
      \hrule height 5mm width\hsize\relax
      \StopLocalStep}}

\StopLocalSteps

\stoptext

Wolfgang
