Luke Farmboy White Neck. Factory error?

Hello big brain variant collectors!

Quick question about this guy. I've seen a couple of these Luke Farmboys with completely white necks. The hands seems to be pale too. Are these simply factory errors or is the whiteness caused by something chemical/plastic related?

Here's an example. Not my photo but from eBay.

Good question Christian. Without seeing the figure inhand, my first thoughts are factory error. Although the hands are pale, you can still see a pink tinge. The neck looks pure white suggesting that it is unpainted.

Was this one on facebook recently? As I saw one with a white neck posted there.

That makes sense Steve. Thanks.

Not sure if it's the same one.
