I don't know anything about dutch. But I do know that Chestnut and steel are too different things. That wouldn't be called chestnut in any breed I know of. It would be steel. Looks gold tipped, the ones with the white/silver are silver tipped. So they are Gold tipped black steels and Silver tipped black steels. These colors could have a totally different name in the Dutch breed, but in Mini lops that would be what they would be called.
