I saw a young woman today with rich, shiny, dark black hair........that had colored her hair at the very back of her neck a golden blonde!  She had it wrapped up in a bun and it had these cool colors all mixed together.  I complimented her on her coloring work.  She took it down, and there was a huge underneath section from ear to ear that was bright golden blonde while the rest of her hair on top was a shiny deep black.  It was just simply beautiful!  If she were to flip her hair over her face it would have been mostly blonde.  Her dark hair was so shiny and looked like pure silk!  Have you all seen such a coloring job before?

I've seen people do the reverse, dying only the top blonde while keeping the rest dark.  It gives the illusion that they are totally blonde, unless they do a bun or ponytail.  

I see the 2-tone look everywhere. Can't stand it. "Am I blonde or am I brunette? How 'bout both?" How 'bout not? Just my opinion.

I agree with Angelspun.  It makes you look indecisive.  Isnt it also hard on the hair, and what about maintaining it?  Just my opinion.
