Your rabbit's color looks like the wild-type coloration - definitely not chocolate. In some breeds, the wild-type color is called Chestnut or Chestnut Agouti (or even Agouti, depending on what part of the world you live in). Your rabbit appears to be Rex coated; the Rex breeds have a particular version of Chestnut that is called Castor. Castor is a deeper, richer shade than Chestnut, and from that angle, it's hard to tell which your rabbit is.
As for the red urine - some rabbits lack an enzyme that is involved in digesting a certain protein. Without the enzyme, the protein doesn't go through a final step in digestion, and instead of getting used, it gets excreted in the urine, and for some reason this turns the urine a bright orangey-red color. This is a genetic condition, so is "normal" for these rabbits; and there is nothing to be done about it. It's a fairly common situation, and as far as I know, the rabbits that have this condition are perfectly healthy otherwise.
