For me I found an other solution:
http://www.dankoweit.de/Skripte/metarkarte.js

Look at the function "METARKarte_Stationen_erneuern(liste)" in my
script. In this function some icons are renewed and the color of the
label is changed:
l_f = l_Stadt.getFeatureByFid(daten[0]);
if (l_f) {
 l_f.attributes.text = daten[4];
 l_f.attributes.fcolor = daten[3]; // <-----
 l_f.attributes.aktuell = true;
}
and then redraw the layer

First define the color-attribute of the styleMap like this:
fillColor: "\$fcolor"

I hope this will help you a little

Best regards

Jürgen
