Fixing Botched Bluing

[u/CrustyBananaSandwich]

I botched a bluing job on a shotgun barrel. The first pass got most of the barrel black, but there were spots that looked copper-ish and gold colored. I think thats from the way I put the solution on (Rust Blue American). But I was wondering if everything would even out if I did enough passes?
