So Star Dragon World's tortoise is green. And this one who is named after the same Tortoise that both are based on is green.

I get that in fictional media black and green are interchangeable for whatever reason, but how come both Tortoises ended up being green instead of black? Seems kind of weird and a bit too coincidental for it not to be on purpose.
