I'd agree in principle with a very dark color, but am concerned that black might be extreme... What else will be in the room in terms of furnishings, other wall colors, flooring, etc.?

On the first floor, I do have a 55" in wall mounted tv with a grey background. This by the way looks great. I don't want to replicate the grey color again in the basement.

Are there different shades of black that won't be too extreme?

Big avocado leather sectional seating facing tv.

We painted our FP brick wall black (thread with pics s/b floating around home dec forum). No TV on that wall, but there is a gas insert so you might gat a lillie bit of an idea how it would look.

We use BM's Black, just plain old' Black, mixed up in Aura matte finish.

Dark colours are great behind a wall mounted tv, both for camouflage and making the images clearer and criper. But if you aren't working black into the scheme it might be a bit of an abyss. It's hard to suggest a variation on black that won't replicate your upstairs grey, maybe a brown black as in swell dwellings photo? I have seen playrooms/family rooms with tv's mounted on black chalkboard walls (quite whimsical and perhaps messy) but an interesting spin nonetheless. We have a deep grey on our tv wall and I wouldn't go back.

Black is good in small doses. Especially being a basement, unless you really want the cave feeling, I wouldn't go there. If you do decide to go with the black, you will need to use LOTS of Edison's lights to not make it feel like a dark abyss. You need to work with a lot of texture and lighter colors to offset the black. For example, in the room posted by SwellDwelling, they used backing in the book cases, recessed lighting, lots of natural light, a white fireplace surround, and the texture of the molding on the bookcases to add some life to it. Flooring, art and furnishings are all light and bright. The ceiling is white. Even at that, without being in the room, it feels heavily weighted toward that black wall.

Since your couch is avocado, I'm thinking a rich coffee brown, or possibly a dark teal or peacock might give you a great deep background that's less cave-like than pure black.

I think something like BM Shadow or Galaxy (almost a black purple) would look great if you are keeping the avocado.

Thanks everyone. Here are pics of the sectional (I had to move to 1st floor to allow for basement framing work to be done). Notice that underside of the cushion is a chocolate color. Avocado color is a bit darker.

i have a friend who painted the tv wall in their theatre room and it looks great and the tv doesn't 'stand out' so much...her wall space showing probably is abit less than yours tho.
if i were to do this i would probably go with black rather than brown---the purpose is to mask the tv-not coordinate with the couch...

i'm not sure what the green room picture is illustrating-i would balence the black out in the room with some accessories/wall pictures, etc and personally would choose a different wall color and would not have such light carpeting...

It looks like you're constructing a home theater of sorts. If so, you'll be watching movies in a darkened room. There are very good reason for not painting the wall behind the flat panel screen black. A middle gray with diffuse back lighting behind the TV panel would be optimal for viewing comfort.

Search Google for some home theater setups. I think people get a little crazy trying to nail a particular back light color temperature, but the existence of back lighting alone makes a huge difference.

I included a link to one of many resources you can find on the subject.

Here is a link that might be useful: Home theater back lighting

A vote to paint the back wall in black/darkest chocolate brown -- and then use lots of that dark color around the whole space. Just be sure to add lots of lighting options!

Also -- check out sherwin william 6164 "Svelte Sage" -- might be a close match to color of the sofa -- and might work for adjoining walls.

Here is SW Wet Seal. Great color - looks black by day but incandescent lighting brought out the chocolate tones at night.

My heart still swoons anytime I see this pic.

It is only one wall and paint. If it turns out that you don't like it you can always paint over it. Will you have anything else on the wall?

The only thing on the wall will be built-in speakers (see original posting of example of speakers in the walls).

knot2fast, interesting info about backlighting. I think that the samsung tv helps to create this backlighting...not sure though and I'll make sure to talk to the tv salesperson about this issue.

Here is the grey wall on my first floor. If I do go grey in the basement, I will definite choose a darker grey.

I've seen pretty room on here that use black fox. get a sample and try it out

With a 65" TV that's not a lot of wall left when you think about it. And I notice it's not your widest wall either. I say go for it - either the dark chocolate or black. It sounds like that is what your gut is telling you to do, and that's what you want. You usually can't go wrong when you go with your gut. With those other bold colors, don't start second guessing yourself now! Be brave and forge on! :) At most, if you HATE it, its a gallon of paint.

I do agree in a basement lighting will be key - with dimmers of course for TV viewing. And as someone else suggested, you really should add a few "grounding elements" of black on the other side of the room. They don't have to be large pieces - maybe no more than a small decorative item or two such as a lamp base or shade that is black, or a knickknack or painting with some black in it.
