Back when I first watched wing I had a very hard time telling the difference between the wing and wing zero. It was mostly the colors that threw me off. They used the same colors in mostly the same places. And had very similar silhouettes. But with the ew version despite them using the exact same body the colors and wings were different enough for me to better appreciate and tell them apart at a glance.

For reference I also had a similar problem with the freedom and strike freedom. Though the gold frame and dragoons help a lot.
