Rosewood looks never agreed with me although there are some Brazilian rosewood slabs that look awesome.Fiebings leather dye is a solution to make it at least jet black but lately i found out that if i finish it with something(either lacquer or superglue) to make it glossy and a bit polished it actually doesnt look half bad...

But they do both have very hard and somewhat dark colored wood. https://en.wikipedia.org/wiki/Terminalia_elliptica https://en.wikipedia.org/wiki/Dalbergia_sissoo
