If you really are delivering style data with your features (feature 
attributes with colors for example), you can use those attribute names 
in your symbolizers.

See the doc Chris put together for this bit:

var s = new OpenLayers.Style({
   'pointRadius': 10,
   'externalGraphic': '${thumbnail}'
});

That would assume you have a "thumbnail" attribute in on your feature 
(in your GML).  You can imagine the same for fillColor etc.

Also see the style related examples:
