Frankly-I'm not sure. Not a big fan of accent walls too, unless architecture supports this choice somehow.. But it doesn't mean it can't be done-or that you won't like it. There are many ways to work with colors, and some are fairly non-standard, and they surprisingly can work..sometimes. Which wall do you want to do in gray? (or-which one you want to feature as white?) (I googled Intense White by the way..I'm sure it shows differently from what it is in reality though, because Gray Owl is right next to it, and reads quite different from your samples..:)

Jenna, the 'Well, duh' was a bit condescending, considering you have given people nothing to look at in an attempt to help you. How can we help you when we have no idea what the room looks like and where the sofa is? Celerygirl does AMAZING mock-ups for people when they supply pictures, so they can see how something will look. We don't know your colors, what your sofa looks like or what the wallpaper looks like. If someone came up to you and said, 'Accent wall.', wouldn't you ask them what they were talking about? Here's an example of a post that gives enough info and a pic, so people can give their opinions - [https://www.houzz.com/discussions/will-a-white-cream-carpet-be-a-mistake-dsvw-vd~5463113?n=48[(https://www.houzz.com/discussions/will-a-white-cream-carpet-be-a-mistake-dsvw-vd~5463113?n=48)

Again, too much metal, too much matchy stuff. Don't buy any more metal stuff. Don't shop for wall items at the big box stores. Hit second hand and antique shops or some interesting art, No More Metal!

Please clarify this statement... "I like more war, colors like the beige or light tan to coordinate with each other." Also it is hard to recommend colors without some idea of the space and how the rooms relate to each other. Do you have a floor plan, sketch or pictures that you can post to help us give you ideas? Whole house open concept or 3 separate rooms with doors or clearly defined separations for different colors of paint. Also what color & type of flooring, furniture, cabinets, rugs, art etc... Without any of the above I can say I like the following colors & you might start your paint journey with:
