Make fondant body. Tint 2 oz. white fondant dark blue using color combination provided. Combine Royal Blue and a touch of Violet icing colors to get dark blue color shown. Roll into a smooth ball, then form into a cone with a wide tip on the narrow end (this will form the head). Make sure neck is smooth and thinner than body and head portions.
Press fondant lightly against surface to flatten one side. Bend narrow end down to form head.
Using ½ in. ball of white fondant, roll small cone. Using small amount of icing, attach to head for beak, trimming as necessary.
Using ¼ in. ball of white fondant, roll small strip using fondant roller with pink guide rings. Taper one end to form eye piece. Using damp brush, attach to head. Press Black Sugar Pearl into eye piece to form eye.
Using Lemon Yellow icing color, tint ¼ in. ball of white fondant yellow. Using fondant roller with pink guide rings, roll out yellow fondant.
Using craft knife, cut 3 to 5 strips, measuring 1 in. x 1/16 in. in size. Using fingers, press and shape one end into a triangle (wide end at top) to form peacock head feathers. Let set, about 1 hour.
