new hair color Lighten up!

The photograph below is the old color. You can see is a dark brown with gray accents. I have a lot of makeup on in this picture. I know it doesn't look like I have any on. The bottom picture is the new hair color. I have no makeup on in that picture because I am a low maintenance woman. I like the look with the lighter hair. I think it makes my face brighten up. Would you change your hair color?
