Fade to black (well maybe dark brown)...

So I am thinking about going back to my natural hair color in preparation for business school a.k.a. me having no income.  I'm not 100% yet because I LOVE my reddish gold color, but it may be best.  If I do, I think I will just use color rinses in dark brown until my hair grows out, which will take FOREVER! I will keep you all posted with my decision!
