Yellowheart

Yellowheart, Pau Amarello, Heartwood color ranges from pale to golden yellow, darkening only slightly with age. Sapwood is a pale yellow/white. Commonly referred to as Pau Amarello— which is Portuguese for “yellow wood”—few woods are as consistent and vibrant a yellow as Yellowheart. The wood is also sometimes sold as Brazilian Satinwood, though it is not to be considered a true satinwood.
Yellowheart has an unusually high amount of radial shrinkage when compared to its tangential shrinkage, giving it a remarkably low T/R ratio.
