THE BLACK STAR stands for the lodestar of African freedom

PINK is associated with the female essence of life. It is viewed as red rendered mild and gentle, and therefore associated with tenderness, calmness, pleasantness, and sweetness. According to Akan social thought, these attributes are generally considered as essential aspects of the female essence.
RED is associated with blood, sacrificial rites and the shedding of blood. Red-eyed mood means a sense of seriousness, readiness for a serious spiritual or political encounter. Red is therefore used as a symbol of heightened spiritual and political mood, sacrifice and struggle.

WHITE derives its symbolism from the white part of the egg and from white clay used in spiritual purification, healing, sanctification rites and festive occasions. In some situations it symbolizes contact with ancestral spirits, deities and other unknown spiritual entities such as ghosts. it is used in combination with black, green or yellow to express notion, spirituality, vitality and balance.
GREY derives its symbolism from ash. Ash is used for healing and spiritual cleansing rituals to re-create spiritual balance when spiritual blemish has occurred. It is also used in rituals for protection against malevolent spirits. Grey is therefore associated with spiritual blemish but also with spiritual cleansing.
