In your styleMap-definition you have to define some placeholders. Look here:

var sm = new OpenLayers.StyleMap({
 stroke: true,
 strokeColor: "\${strokecolor}",
 fill: true,
 fillColor: "\$fillcolor}
});
layer = new OpenLayers.Layer.Vector("LinearRings", {
 styleMap: sm, ...});

You have to use this like in the following example:

var pf = new OpenLayers.Feature.Vector(...);
if (pf) {
 pf.attributes = {strokecolor: "#123456", fillcolor: "#654321"};
 layer.addFeatures([pf]);
}

Best regards

Juergen
