Ugh, a few months ago I had a similar experience. I can't locate the brand info online (and I forget off the top of my head), but the name was some "reddish blonde" type and the color on the box was this intensely vivid orange-type RED. I dyed my recently bleached (It wasn't pure blonde, but it was very light) hair with it, and it turned my hair this deep, browny, cherry type red. Emphasis on brown, totally not on red. It wasn't even switched out like the other poster's experience (I always check out of pure paranoia)... that's just what that color did. Pigfuckers.
