Body art Uli designs are commissioned by a patron, often after seeing an uli artist's work elsewhere. The patron requests a specific style or motif or leaves the design to the discretion of the artist. Before application, the person to be painted is shaved in order to create a smooth surface. Ufie, a dust or paste made from
camwood bark, is applied to the skin as an antiperspirant. The berries of one of the uli plants, such as
Rothmana whitfieldi or
Cremaspora trifora, are harvested and ground up into a mash. This mash is then pressed through a cloth, producing a yellowish liquid that is stored in a receptacle. Dried uli seeds can also be re-hydrated and then pressed in order to create the dye. Charcoal may be mixed with the uli liquid so that the design is clearly visible while being drawn. The liquid can be applied with a variety of tools, such as a small blunt knife (mmanwauli), slivers of wood, or metal combs. The dye then oxidizes, staining the skin an indigo color that lasts for approximately 8 days. After the staining process is complete, the skin is rubbed with oil in order to create a distinctive sheen.
Murals Uli murals (uli aja) are created using white, yellow, reddish brown, and black pigments. The white color is made from clay, the yellow from either soil or tree bark, the reddish brown from camwood tree dye, and the black color from charcoal. The charcoal color is more permanent than the other pigments, leaving behind designs that are then sometimes reworked into new drawings. A blue color, created from a laundry additive introduced by the British, has also been used by some artists. Before the pigments are applied, the walls are first sized using
laterite (aja upa), a mud slip that fills in cracks in the wall. The surface is then further burnished using fine pebbles (). A final layer of primer, a red mud slip, is then applied to the wall in order to create a three-dimensional surface to work on. Artists apply this slip by moving their fingers in rhythmic patterns, creating curvilinear patterns on the surface of the wall. The pigments are then mixed with water and applied to the wall using the artist's hands, twigs, feathers, or using the mmanwauli (uli knife). Currently, some artists choose to use sponges or paint brushes to apply pigment. The designs are often applied by a larger group of women but generally are designed by the most experienced and skilled. == Usage in Igbo culture ==
