I am unable to chose a colour for my walls in my new theatre.
Any thoughts? The PJ is the Optoma HD 81.

I would try for a khaki/mud with a little bit of red to pick up the other reds in the room and a darker shade of the same for the ceiling.

I couldn't quite get enough red in my quick attempt here:

OK, a little closer and I darkened the ceiling:

Bigmouth provides such a good community service! Can you move to my neighborhood? Colorado is beautiful...and you could build a brand new theater :D

I like the second one - they blend well with the wood.

..and you could build a brand new theater

That would make it worth the move. But First I have to finish 1.0 !

OK, more gray with a hint of red:

Well stop watching DIY network...:o...and get crackin' (kidding)

I'm sure someone will say RED. Here is the red I would use and a darker red ceiling:

I like BLACK with red walls and a black wall for the theater screen.

Give it a shot!

Thanks for the replies, what program are you using to do this? I am not the most computer literate.

I downloaded your Pic. Then opened in Photoshop. I used the select by color command to pick out the white wall. Then selected a color in the color palette area and painted over the selected area.

I then saved the pic and uploaded it to my free Photobuckect account and pasted the link into the thread. Takes about 2-3 minutes.
