Some exterior colors have been shown to be VERY different from the images on the Ford website. I would really check videos to check out the color in "real life" and not judge it.
I personally find the brown OK. It's more off an "off roady/rugged" color than a pretty color.
I would think the brown would darken up with use. Reminds me of the colour of my iPhone leather case from when I first purchased it. Now the case is such darker.
