Visa Question from Ukraine.I just got my visa approval to go to the U.S. How do I know if it is 1 year or 5?

They gave out green cards, blue cards and pink. Mine is green.I dont get my actual visa for a week but want to know if it is 1 year or 5 year visa. Does anyone know this. Please dont say look at your visa, I dont get it for another week or so and I cant contact emby to ask. Thanks
