I;d go auburn. If you have freckles I think this color would be beautiful on you. Like others said I would not go too light because it would be too expensive to maintain and would be too drastic.
Almost any dye that you use will cause your hair to come out darker, or with lots of auburn. The only way to lighten it is to bleach it with the hair product, (not household bleach.) You will have to take it through a lot of red to get it to a blonde color, or even a lighter brown. Best to have it done professionally, perhaps a frost (blonde streaks).
If this is the first time you are coloring your hair, I would suggest you go a few shades lighter. I would not got black or very blond, nothing startling. Unless that is what you are going for, to shock everyone. Or maybe you would like to try just doing blond streaks. That is a nice look, I think, and not as big a change. It is easy to do this yourself, or if you have it done in a salon, they will advise you about color.
