Haute Hue: Red, Yay or Nay?

First Scarlett Johansson then Blake Lively... it seems our favorite blondes are trading in their signature locks for strawberry-hinted reddish hues. Blake's excuse?  She wanted to feel like the character she was playing for her new role in the movie Hick.  Makes sense to me and even though I like her better as a blonde I think she nicely pulls off this color too.

I remember when Scarlett dyed her hair red for her role in Iron Man 2 back in 2009.  I liked it then, but it was also a deeper red and her hair was longer so it was an overall sexier look.  Now, I think her short hair looks better as a blonde.

Thoughts?
