Greenish Jack pop but not GITD

I love all the Nightmare Before Christmas pops and I have a few! This one is weird though since I'm sure he should be white but he actually has a greenish tinge to his face and hands which might suggest that he is GITD but he isn't, so I don't know what is going on with him. The other Jacks are all white. Anyway, he looks good next to the others, regardless.
