Members of Rainbow are active in their churches, schools and
communities.  They raise money for various charities through bake sales,
dinners and car washes, and they extend themselves in service to their communities,
churches and their sponsoring organizations.  Rainbow Girls have many fun
activities and opportunities to make lifelong friendships.
Rainbow Members in good standing, as well as any Mason, Eastern Star
or Amaranth in good standing, any Majority Member of Rainbow, and any parent,
grandparent, or legal guardian of a Rainbow Girl is eligible to attend a meeting
of the International Order of Rainbow for Girls.
No.  The International Order of the Rainbow for Girls is a
service organization.  Rainbow does, however, encourage each member to be an
active participant in the church of her choice.
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 Colors of the Rainbow are represented by seven stations, strategically
placed in the shape of a bow.  Each station is represented by a color, and
each color teaches one of the seven lessons of Rainbow.  The stations and
lessons of the Rainbow are as follows:
Red is the first color station and represents Love.  It emphasizes the
importance of love of home and family.
Orange is the second color station and represents Religion.  It emphasizes
the importance of membership and active participation in the church of your choice.
Yellow is the third color station and represents Nature.  It emphasizes the
importance of spending time in the out-of-doors.
Green is the fourth color station and represents Immortality, It emphasizes that
even though our body dies, our souls live on forever.
Blue is the fifth color station and represents Fidelity.  It emphasizes the
importance of loyalty to the Order and to the Rainbow Girl's family and friends.
Indigo is the sixth color station and represents Patriotism. It emphasizes the
importance of respecting the laws of our country and its flag.
Violet is the seventh and final color 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 State 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.
