The Ritual for the International Order of the Rainbow for Girls is a book of ceremonies used primarily for the Opening, Closing and Initiation of a Rainbow Assembly. Members of the Order recite, from memory, the ceremonies contained in the Rainbow Ritual.

The Seven Colours of the Rainbow are represented by seven stations, strategically placed in the shape of a bow. Each station is represented by a colour, and each colour teaches one of the seven lessons of Rainbow. The stations and lessons of the Rainbow are as follows:

Red is the first colour station and represents Love. It emphasizes the importance of love of home and family.

Orange is the second colour station and represents Religion. It emphasizes the importance of membership and active participation in the church of your choice.

Yellow is the third colour station and represents Nature. It emphasizes the importance of spending time in the out-of-doors.

Green is the fourth colour station and represents Immortality. It emphasizes that even though our body dies, our souls live on forever.

Blue is the fifth colour station and represents Fidelity. It emphasizes the importance of loyalty to the Order and to the Rainbow Girl's family and friends.

IIndigo is the sixth colour station and represents Patriotism. It emphasizes the importance of respecting the laws of our country and its flag.

Violet is the seventh colour station and represents Service. Service is the foundation of Rainbow and emphasizes the importance of providing unselfish acts of service to our home, community and sponsoring orders of Rainbow.

The leadership structure of Rainbow begins with the local Assembly and extends to the province, country and International Assemblies. Each local Assembly is made up of five line officers (Rainbow Girls who lead the Assembly under the direction of a Mother Advisor and Advisory Board) and thirteen appointed officers. The adult governing body of each Rainbow Assembly is known as the Advisory Board and is comprised of seven to fifteen adults from various Masonic organizations or parents of rainbow girls.
