As a perceptive reader might see (or one speaking both swedish and english)? Dorins last name is Grönskägg (Greenbeard) but on his picture he got red beard. The picture is from his young days when he started out as a worker at one of the biggest copper mines in Ereth Luin.

All the copper powder that he got in his beard finally turned it green from verdigris and he got the name Grönskägg. Since then he hasn't washed his beard and there are rumors about what the teammates have found inside it.
