I gave my Wested distressed cow jacket a couple coatings of Pecards and it darkened it up enough to take away most of the tan color. Did the same to a import US Wings steer-hide Legend jacket.
I have a few Indy jackets and the lighter color on a couple of my jackets adds variety. Also have a black Indy Wested to wear with my black boots. Some of my brown Indy jackets range from reddish brown, light brown, medium brown, grey brown and dark brown.
If I was only going to have a couple, would want one dark brown and one black.
My Alden Indy boots also come in various shades of brown along with a dark blue and black.
