First, you should come to the celebration with a profound respect for its values, symbols and practices and do nothing to violate its integrity, beauty and expansive meaning.
Secondly, you should not mix the Kwanzaa holiday or its symbols, values and practice with any other culture. This would violate the principles of Kujichagulia (Self-Determination) and thus violate the integrity of the holiday.
Thirdly, choose the best and most beautiful items to celebrate Kwanzaa. This means taking time to plan and select the most beautiful objects of art, colorful African cloth, fresh fruits and vegetables, etc. so that every object used represents African culture and your commitment to the holiday in the best of ways.
The colors of Kwanzaa are black, red
and green; black for the people, red
for their struggle, and green for the future and
hope that comes from their struggle.
Therefore there is one black candle, three red and three green candles. These
are the mishumaa saba (the seven candles) and they represent the seven
principles. The black candle represents the first principle Umoja
(unity) and is placed in the center of the kinara. The red candles represent the
principles of Kujichagulia (self-determination),
Ujamaa (cooperative economics) and Kuumba
(creativity) and are placed to the left of the black candle. The green candles
represent the principles of Ujima (collective work
and responsibility), Nia (purpose) and Imani
(faith) and are placed to the right of the black candle. The black candle is lit
first on the first day of the celebration. And the remaining candles are lit
afterwards from left to right on the following days. This procedure is to
indicate that the people come first, then the struggle and then the hope that
comes from the struggle.
And then the mazao (crops), and ears of corn are also placed on the mkeka.
At least two ears of corn are placed down on the mat regardless of whether there
are children in the immediate family or not for the children of the community
belong to all of us and every adult in African tradition is considered an
immediate or social parent. Next the kikombe cha umoja (the Unity cup) is
then placed on the mkeka (mat). It is used to pour tambiko
(libation) to the ancestors in remembrance and honor of those who paved the path
down which we walk and who taught us the good, the Tamshi
and the beautiful in life. Then African art objects and
books on the life and culture of African people are also placed on or next to
the mat to symbolize our commitment to heritage and learning.
Daily
Practices
Each evening the family gathers to light the candles. The candle
corresponding to the principle of the day is lit. On the first evening the
family lights the black center candle for unity. On the second day of Kwanzaa
the family again lights the black candle for unity and the red candle for
Kujichagulia (self- determination). On the third evening, the black and red
candles are relit and the green candle for Ujima (collective work and
responsibility) is lit. This practice of lighting the candles for the principle
of the day beginning with the black candle and alternating from left to right,
red to green continues throughout the seven days of Kwanzaa until the last
candle has been lit on 
the
last day of Kwanzaa. While the candle is lit the principle of the day is
discussed. Everyone explains what the Nguzo Saba
principle of that day means to them and how they have
practiced it during the day. After the discussion, a commitment is made
by each and all to practice and promote the particular principle throughout the
year. To close out, seven "Harambee" (Swahili for "Let's
all pull together") are called out. Also various other activities are
organized to practice and promote the principle of the day. These include
working together on projects, studying and learning more on African culture,
sharing narratives and other literature, poems, dance and drama; and making
Kwanzaa items as symbols and/or gifts. All of these are to celebrate the holiday
and reaffirm and reinforce family, community and culture.
