Technically, there are no different “breeds” of dachshunds. Doxies are all one breed, that’s what being a dachshund is. However, they are distinguished in several different types or “sub-breed” categories based on their size and coat type.
Standard dachshunds aren’t necessarily calmer than miniature ones even if we’re used to the idea of bigger dogs being calmer. The color also doesn’t seem to matter much. The only purposed correlation seems to be the coat type.
