Superman vs. Superboy: Orange isn't the issue so much as yellow. If it has any pure yellow, plus red on a blue base, it's a Superman. It can also have orange and I've even seen blended green: those are still Supermans. A Superboy has no pure yellow, just yellow blended with red to make orange, on a blue base. Not sure if it has to have any pure red. And if the orange is a distinct color in its own right, not just a blend of red and yellow, my guess is that it's still a Superboy, or possibly a Superteen, as I've seen some call them.
I don't have any problem with anyone giving new names to anything as long as they say that it's a name that they just created. Then let popular opinion decide if the name should stick. And if it already has an established name, then why not call it that to avoid confusion.
It took me a long time to see past all the names and hype, and just buy according to what I like.
