Hi Julien,

your question might better fit on the users list, but I'll answer anyway.

You could try to add a Vector layer with a polygon-feature that is style 
partly-opaque; this shoukd do the trick if I got you right.

Further questions should possibly be sent to 
openlayers-users at lists.osgeo.org.

Best regards,
