Can be normal: Vitamins, foods, slight dehydration can produce dark urine. If persists, I would recommend a urinalysis test to be sure.

Yes: Concentrated urine is generally very dark, and dilute urine (such as after a large amount of fluids) is quite clear. The urine won't stay clear, once the extra fluid has been eliminated.
