MacBook Pro :: Blurry Pixels With Multiple Colors Show Up On White Background

So my problem with my Macbook Pro's pixels is many of them look blurry and are multiple colors almost like a rainbow. They also only show up on white backgrounds, not black. Some of them are in clusters and others are spread out. One of the clusters is very annoying and looks like a big blurry dot on my screen. I am hoping to take it in to the apple store and see what they can do about it because it seems like it is getting worse. I am assuming these are all dead pixels but I am not certain.
