Tip of the Day – Midnight Walls

If you are really serious about building a home theater, and you really want to maximize the results, it’s not just the equipment that is going to make your theater stand out.  Choosing a proper wall colour is one of the most important decisions to make when building a theater.

Everyone knows that light is absorbed by the colour black right?  That’s why baseball players put that paint under their eyes, that’s why you don’t wear a black t-shirt to the beach.  The same rule applies when painting your theater room.  A projector throws light over a large distance in an effort to reflect off of the screen.  Said screen will have, if it’s a good one, reflective attributes that will multiply the amount of light returning to the viewers eyes.  This is what is known as screen gain.  Generally the higher the screen gain, the brighter the image.

“What does this have to do with the wall colour?” you ask.  A projector’s lens is built to focus in a rectangular shape at a ratio of 16:9.  However, the light that leaves a lens will always, always, always create spillage around the intended target.  If the walls surrounding your screen are white, they will reflect this spilled light.  This reflected light will not only draw your attention to the walls, but will also shed light on the image causing it to wash out.  If they are black, they will absorb it.  It’s as simple as that.

Unfortunately, black walls are not in everyone’s design scheme.  Ideally, you should bite the bullet and work a black wall into your scheme, at least, on the wall the screen is mounted to.  If black is just plain not an option, choose the darkest colour you can live with.  Trust me, you will appreciate it in the long run.

Look at the way this image stands out on the black wall!
