Zulu beadwork language uses the triangle as base geometric shape and seven base colors: black, blue, yellow, green, pink, red and white which can be used to convey positive or negative meaning.
The triangle represents the father, mother and child. A downward triangle represents an unmarried woman while an upward pointing triangle represents an unmarried man. Two triangles joined at their base in a diamond shape represent a married woman, while two triangles joined at their tips in an hourglass shape, represent a married man.
