I went with the dark blue color.  It adds great coverage to my plaid loveseat.  You can't see through the fabric at all.  It is a little wrinkly after opening, but nothing that a steamer or iron won't take out.  I purchased the exact same brand 4 years ago in the lighter khaki color and it lasted a long time until thinning out after years of washing and wear.  I would definitely recommend this as a cheap and easy way to update a worn loveseat or sofa.
