Go darker, right?

Am I right that a darker brown looks better on me? My natural hair color is the lighter brown color. I've got some VERY grown out babylights.

My natural hair texture is seen in the last pic, wavy curl.

I'm thinking of doing Wella Color Charm demi-permanent 6N or 7N to dye my hair darker. Might start with 7N since I know the outcome tends to be much darker than people anticipate, and then if I want to go a little darker, I'll do 6N. Buuut that's only if people agree that I should go darker.
