The difference I have seen between the blue and the green tape has to do with the tackiness. The green tape is stickier and adheres better to what you are applying it to. Depends upon what you are trying to mask off though. For example, I painted the entire interior of my house using the blue tape and swear by it. I had read somewhere that the green is for lacquer (and even glass).
