The sapwood of this hardwood is milk-coloured to almost white and susceptible to discolouration. The heartwood is light yellowish-grey to pale brownish with a matt sheen, the darkening is very slight and leads at most to a light browning. Sen originates from the non-tropical forests of East Asia and is used as decorative veneer or solid wood due to its wood appearance.
