That’s not correct. There are other forms of IP besides copyright, such as trademarks, patents, or even trade secrets.
What you are saying is somewhat true for US copyrights (and patents) per the copyright clause in the US Constitution. But mind that typically copyrights are owned by the employer of the creator, who may be a writer, even a programmer, photographer, or any other such professional who may not be considered an “artist”.
You would probably not consider yourself an artist for writing comments here, but you get copyright nevertheless.
European copyright has a very different philosophy behind it, which does not consider the public at all. It’s quite harmful to the public, actually.
Generally no, but I wouldn’t rule out that it might be possible in a limited way in very specific circumstances. You wouldn’t be able to stop others from using certain colors.
A specific color scheme might also be used as a trademark.
Justice delayed is justice denied.
