Is Mewtwo #63 Breakthrough Supposed to be white or purple?

[gdark]

Just curious if anyone else owns one or knows if there is an error in print for the mewtwo #63 from breakthrough. I recently picked up a psa 10 copy and noticed Mewtwos big head is stark white/grey, when compared with other copies I’ve seen online and in person being purple/bluish.

It’s supposed to be purple. My first thought was UV damage based on the slight bluish hue of the card, but I suppose it could be a printer variant. If you buy a “normal” copy of the card, you could compare them under a loupe.
