The official blazon is "Vert, a swan argent rousant, armed sable" (Norwegian: I grønt en oppflygende sølv svane).

The swan has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

This design was chosen to symbolize of the large number of these swans that migrate through the area each year.
