so in my less than helpful google searches, a lot of the eggs that are coming up as being pink, or possibly being pink "if you're lucky" are coinciding with breeds that have "light brown" egg colors, BUT it's not affected by the different leg colors, as far as I can tell... I mean based on what we have it isn't but who's to say what kind of crosses the people from the far reaches of the internet are getting their special pink shelled layers from. seeing as how the brown pigment is the only scientifically proven color, other than blue; I'm going with pink is just a variation on brown. I really can't seem to find anything else on it. there don't seem to be any scientific articles on it at all.
