Hey all!
been a while since ive visited here, but figured it was the best place to ask, Ive been collecting the wheels from Roboriders (among other collectibles!) for a while now and came across the one on the right, initially I just thought it was faded or something, but on closer inspection, the eyes are blue instead of green and the yellow seems to be completely absent as well as the red being purple. All the other coloured wheels that ive got with this printing match the one on the left. Is this a known variant? or a printing error or something else entirely?
thank you!!
