which nightwing color is cooler

[ArtimusX]

I saw Blue as well for the most part. However i could see how Red would look badass IF you were cosplaying with a team or buddy who also had a Red Bat Symbol. But if you're going individual, Blue all the way

Technically, if we're debating stealth, red is the color that's hardest to see in the dark, so blue might not actually be better for hiding.

...but I also like blue better.

And, if you were in an all-red Batfam like ArtimusX mentioned, being the only one wearing blue might not look as cool...but it would be really funny, to me at least. And it'd be aggressively in character for Dick Grayson.
