Those colors are fine. Goes along with the flooring and very easy to accessorize. We added this new type of 3D faux tile around the back-splashes of the sinks, a few pieces of artwork, greenery with the help of velcro, and some colorful throw pillows. Really helped bring out an inviting feel to the interior.
One other thing i forgot to mention about my GTXL, for some reason they did not put toilet paper holders in either of the bathrooms! They didn't put any towel racks either. I was able to find the same material (brushed stainless) in a few different styles at Bed, Bath & Beyond and the ones we went with seem to be an exact match to the style of the faucets in the coach. Take a look at your bathrooms while you are there to see if they installed the toilet paper holders and towel racks.
