Heartwood is a reddish brown. Well defined sapwood is a pale yellowish white. Color tends to darken with age. Pieces containing pommele or blistered figure are sometimes sold under the name Afzelia xylay, which is a shortened version of the botanical name of a particular Asian species, Afzelia xylocarpa.
Afzelia is on the IUCN redlist and is now an endangered type of wood. Expect to see it disappear from many catalogs, much like Boire has.
