The purple stripes are purple hearts
Purple heart is a tropical wood that turns purple. Sometimes she is called Amarant, to the French trade name (Amarante).
This wood type finds applications in furniture making, parquet floors, for industrial applications, but also billiards or in the construction of guitars (especially in the sides and backs, except for the test).
Dutch artist César Domela Nieuwenhuis sometimes used this kind of wood for relief.
The wood is supplied by species of the genus Peltogyne, from tropical America.
