Welcome to the Forum!
If you post a couple of photos
, that will help us give you better suggestions. Take some time to consider the options before continuing.
If you do paint, paint the end of all the ferrules so they match each other. No matter what those little ends won't match the rest of the rod. But the only time they are easily noticed is in the rod bag.
Another option is ferrule rings. To get an idea what they look like, see this Rod Photos post
, the 11th photo gives a good view. Ok, that's a high bar to shoot for, but you can see how the metal rings cover the ends of the rod blanks. Run a Google search for "ferrule ring fly rod" for possible vendors and advice.
