What dose it mean if your puke is green?

Possibly bile.: Green coloration of the vomit could be from the breakdown of food in the stomach, depending on what was eaten. However, the presence of yellow or green bile in the vomit, a fluid made by the liver, can cause this. This is called bilious emesis. Often, depending on the age group, it is caused by blockage of the intestine, causing a backup leading to vomiting. See your doctor for evaluation.
