Just for fun, included a couple different variations. Admittedly the lighting in my room and my phone’s camera both suck, so I’ll try to describe how it looks to me.
Shadowless and Japanese - both the darkest artwise to the point of crushing the gradient in the background a bit
4th print and German 1st - both lightest art and rest of the card wise
English UED and Base 2 - see below
Chinese 1st - Art seems to be more saturated than Eng UED and the rest of the layout is distinctly orange
Base 2 layout seems slightly more orange to me. For the art itself, Magnemite is bluer in UED while more grey in Base 2.
