Foamy urine is not so much a color issue as it shows your urine is protein heavy. If you have a lot of protein in your urine, the protein reacts with the air and water, creating the foamy urine.
Sometimes you may experience foamy urine after eating a lot of fish, chicken and other meats. These meats contain muco-proteins. If your body is not breaking down these proteins efficiently, the protein is usually expelled from your body in your urine. The proteins then produce foamy urine.
Now if you continually experience foamy urine, see a doctor. Foamy urine can be a symptom of kidney problems or a gallbladder problem.
