When we first see Vegeta, while he is in space headed to Earth and on the Bug Planet he looks like this
But when he gets to earth he undertakes a sudden colour change to this
Now at first since Vegeta is initially off world i though that maybe it might have been the local suns had a different colour light to Earth's, but then that wouldn't explain why his scouter would remain the same colour.
I am wondering, is Vegeta's colour change a result of his design changing mid series? or is there a reason why everything but his scouter changes colour when he arrives on Earth?
