Creates a plane of the specified color at the specified position and rotation.
parameter: color The color of the plane.
parameter: x The x position of the plane.
parameter: y The y position of the plane.
parameter: z The z position of the plane.
parameter: rotationY The rotation of the plane on the y axis.
