Painting a Media Room or Home Cinema in London
How to paint a home cinema or media room — blackout dark walls, ultra-matte finishes to eliminate glare, and integrating acoustic panels seamlessly into the decoration.
A Room Designed Around a Single Experience
A media room or home cinema is one of the most satisfying rooms to decorate because the brief is unusually clear: everything should serve the viewing experience. Colour, sheen level, light absorption, acoustic integration — all of these feed directly into how immersive and comfortable the room feels when the screen is on.
We've decorated media rooms and dedicated cinema rooms across central and south-west London, and the principles are the same whether you're working with a modest 4K projector or a full Dolby Atmos installation.
Why Darkness Isn't Just an Aesthetic Choice
The most important thing to understand about a dedicated cinema or media room is that the walls should absorb light, not reflect it. Every surface that reflects ambient light back into the room — whether it's the screen's backlight, the projector throw, or the spill from LEDs around the back of the TV — reduces perceived contrast on screen.
This is why professional cinema design specifies very dark, very matte surfaces throughout. It's not purely a style preference; it's physics.
In a home setting, you have more flexibility than a true commercial cinema — you may want the room to function as a living space in the daytime as well as a viewing room in the evening, which means some compromise on the extremes. But the principles still hold: the closer you can get to a dark, matte, light-absorbing environment on all surfaces, the better the viewing experience.
Choosing the Right Dark Colour
Not all dark colours are equal for cinema applications. The critical properties are:
Low light reflectance value (LRV): this is the percentage of light a painted surface reflects. For cinema rooms, you want an LRV as low as possible. True black paints (Farrow & Ball Pitch Black, Little Greene Obsidian Green, Dulux Trade black) have LRVs below 5. Very deep blues and charcoals typically sit between 5 and 12. Mid-dark colours — Hague Blue, Mole's Breath, Stiffkey Blue — have LRVs from 15 to 30, which may be sufficient for a media room that doubles as a living space.
Warmth vs. coolness: pure cool black and blue-black tones can feel clinical in a home setting. Many clients prefer a warmer dark — a very deep charcoal with a brown or green undertone rather than a blue one. Farrow & Ball Off-Black, with its slight olive warmth, works particularly well. Edwards of Ironbridge makes a deeply saturated range of heritage colours that includes some beautiful warm blacks.
Consistency: the ceiling, walls, and ideally the floor covering should all be in the same family of dark tones. A dark ceiling matters as much as dark walls — a pale ceiling reflects the screen's light back into the room and creates an uncomfortable halo effect above the viewing area.
The Ultra-Matte Finish Requirement
The sheen level of paint in a cinema room is just as important as the colour. Even a standard low-sheen emulsion will produce hot spots and reflections in a darkened room when the projector or screen is the primary light source.
What you need is a true ultra-matte or dead-flat finish with essentially zero reflectance. Options include:
Farrow & Ball Estate Emulsion — one of the flattest finishes commercially available, and available in all Farrow & Ball colours including the deepest darks
Little Greene Absolute Matt Emulsion — similarly flat, with excellent colour depth and minimal sheen
Specialist cinema paints — there are dedicated products marketed for home cinema applications (Seymour Duncan, Acoustiblock) that are formulated specifically for high-absorption properties
We would not recommend using standard trade emulsion, even in a silk or flat finish, in a dedicated cinema room. The difference is visible and it undermines the investment in the AV equipment.
Integrating Acoustic Panels
Most well-specified cinema rooms include acoustic panels — fabric-wrapped frames or rigid foam tiles positioned on walls and ceiling to manage reflections and reverberation. The way these panels are integrated into the decoration significantly affects how the room looks.
Matching the fabric to the wall colour is the simplest approach and produces the most seamless result. Most acoustic panel manufacturers offer their panels in custom fabric colours; specifying a fabric in the same dark tone as the wall means the panels read as part of the surface rather than as additions to it.
Painting panel frames to match the wall is also important — bare timber or metallic frames draw the eye in a dark room. We apply the same wall paint to any visible framework around acoustic panels.
Recessed panels — set into a rebated section of wall so the face sits flush — eliminate the shadow line that surface-mounted panels create. If the room is being built out with studwork specifically for acoustic treatment, it's worth discussing panel recessing with the builder at design stage.
Practical Considerations
Cinema rooms are frequently in basement or lower-ground-floor locations in London homes, which means the moisture considerations discussed in our wine cellar guide apply here too. Check for damp before painting, use a moisture-resistant primer where needed, and ensure adequate ventilation.
Cable management is easier if you paint before AV equipment is installed. Where possible, we prefer to complete all wall and ceiling painting before the screen, projector mount, and speaker brackets go in.
