Which hair color looks better on me?

Cindy

Thanks, everyone. After 4 years of not dying my hair I finally decided to dye my hair couple of days ago. I was scared the one on the left would not look good. The one on the right is my natural color. Personally, I like the dark color on me but I wanted a change since this year I turned 30. I think after a few months I might go back to my natural or do a balayage.
