Hawaiians also had many other uses for the tree, including: leis from the shells, leaves, and flowers; ink for tattoos from charred nuts; a varnish with the oil; and fishermen would chew the nuts and spit them on the water to break the surface tension and remove reflections, giving them greater underwater visibility. A red-brown dye made from the inner bark was used on kapa and aho ( Touchardia latifolia cordage). A coating of kukui oil helped preserve ʻ upena ( fishing nets ).  The nohona wa ʻ a (seats), pale ( gunwales ) of wa ʻ a ( outrigger canoes ) were made from the wood.  The trunk was sometimes used to make smaller canoes used for fishing.  Kukui was named the state tree of Hawaii on 1 May 1959  due to its multitude of uses.  It also represents the island of Moloka ʻ i , whose symbolic color is the silvery green of the kukui leaf.
