Using braces

I'd like to run the code:
`numeros4 = TexMobject(
"\\mathbb{N}",
"=",
"\\{",
"1",
",",
"2",
",",
"3",
",",
"\\ldots",
"\\}"
)`
cause I wish I could change the color of the braces separately. But I got this error:
`Exception: Latex error converting to dvi.`
I've already tried using the command `Brace()` or the ideas found at reddit, but it didn't work at all. Is there a way to make it possible?

Thanks!
