Beauty is in the eye of the beholder. The objective of feature wall is set the mood of the house. Feature wall is the attention grabber.

Is the wall just painted? The color of the newly painted wall take a few days to set.

I agreed with Eleganz Concept to paint all the way to the ceiling. Enhance the height.

Once your furniture moved in, it will tone down the color.

As how to tone down the boldness is how you use your creativity & imagination.

10 ft TV cabinet is a bit too long. Do you have space to fill in a pair of speakers for home cinema? I'm sure your kids will love them.

There are many ways to build feature wall. Exotic will be expensive wall paper, textured sculpture, nice ceramic tile, hi gloss black panel, glass etc...

Painting is the cheapest of all.

Creating your personal memory lane with framed photo arranged in random will be very nice too...
