The national colours of Australia are green and gold, as proclaimed by Sir Ninian Stephen, the Governor-General of Australia on 19 April 1984. The exact colours are specified as being Pantone Matching System numbers 116C and 348C, and always referred to as "green and gold". Green and gold are the traditional team colours of Australian national sporting teams, and nearly every current Australian national sports team wears them, although the hues and proportions of the colours may vary between teams and across eras. It is widely believed that the colours were chosen because they are the dominant colours of Australia's floral emblem, Acacia pycnantha (the Golden Wattle).
