how the hell does it turn pink? did you have blood on your hands or something? i don't even want to know how a nunchuk turns brown.

My analog stick is very slightly yellow (that's to be expected....I always wash my hands before I play but it's still a bit yellow) but the pink thing is really odd.

The pigment that The manufacturer uses in the plastic chemically reacts with substances around it. sweat, dirt, what-not.

Most of the time yellowing is caused by exposure to sunlight.

Pink? Hmm... I would like to see what pigment they used to make white.

My one nunchuck cord is a very light blue in some places. The analog is completely blue. On one of my Wiimotes 1\2 buttons are a little blue, the b button and the side of the remote is a faint blue.

Wii needs black remotes/nunchucks :(

weird

i think that sweat has something to do with it!

Meh. I think it looks nice :P

It seems like the result of direct exposure to sunlight.

I can't say mine have turned any color, however from the kids I watch at some points the Wii remote and nunchuck I make them(and only them) use has gotten dirty. The strap turned.. black and the analog turned a yellowish color..

What, are you sweating all over the cord too? I don't get how that would happen...

Anyway, I think the joystick might be a bit discolored, but if so only very slightly.
