Flag of Alberta
|Design||Ultramarine blue with the shield of the Alberta arms centred on the flag. |
Around the time of the upcoming centennial celebration of Canadian Confederation petitions were submitted in November 1966 to Premier Ernest Charles Manning by the Social Credit Women's Auxiliaries of the Alberta Social Credit League to give Alberta its own unique flag. The flag was designed and approved as the official provincial flag by the Alberta legislature on June 1, 1968. 
The provincial colours, adopted in 1984, are blue and gold (deep yellow); they are also referred to as "Alberta blue" and "Alberta gold", appearing on the flag/shield in the sky/background and wheat background, respectively.
