i picked up some green (emerald) corydora's a little while ago. I just found a couple of things. The store which I got them from sell dyed fish (Big Al's). I also found out that these can be dyed to enhance their colour. Is there any way to know if these fish are dyed?

Try a web search on Emerald Cory, if that doesn't show many hits try Brochis Splendens. I think that's the proper name.
As for dying them? They may well be fed color enhancing foods, but all the info I've found never mentions injecting them.

don't think that that is it, the body looks the same but my fish looks more like

So more like this one then?
Another pic It's the same fish as the first picture link I posted. By a different photographer though.
Search on Planet Catfish.. the pics I've posted are of the same type of fish but show the variations in color with age and angle of flash etc... you may find more info there about the possibility of artifical coloring of the fish.
This is a link to the thumbnails and the stats for this fish. Info

The fish that I've seen that are dyed have a distinct color. They are usually a gawdy neon color.

Correct me if I'm wrong, but I don't know of any cories that are dyed. I know glass fish are dyed neon colors, as well as some others, but emerald cories are common, and naturally that color. Hence the name. I think you're safe, as are your fish. 
I've seen corys dyed blue. I noticed them in one LFS because they were an unusual ocean blue color that caught my eye but sure enough, when I looked more closely the coloration was only on the tail section in the larger ones. The clerk there denied that they were artificially colored but asking at a more reputable store, another staff member assured me they were albinos that had been dyed, there was no natural coloration like I described.
Keep asking if the colors you've seen occur naturally... I have no idea. Does the coloring do all the way across the body or have any variations that seem artificial? On close inspection I could see the albino characteristics of the blue ones in the LFS- and I shudder to think how they colored them!
