It’s very important to me that the client gets the colour right as then I know they’ll be happy with the job and so, happy with us.
So a few tips on choosing colour:
Don’t make final colour decisions based on colours seen on a computer screen. Colours on a colour chart are more accurate but samples painted on a wall will give you certainty.
If you’re putting up swatches of colour on your walls place some in direct light and others in shadow. A colour in direct light looks different to a colour in diffused light, so much so that I have at times been sure it really is a different colour.
The Dulux website has lots of suggestions, including using their Visualizer App. They also have a Virtual Paint Advisor who is actually virtual but doesn’t act like a total robot.
Ask your decorator what colours he’s had success with. For example, me who says; if looking for a slightly, off-white that doesn’t hint of any colour, try Dulux Timeless, it’s very easy to live with.
By the way I’ve painted both walls and ceiling in many rooms with Timeless. If that sounds bland, it’s not, but you could paint, on one wall, my most favourite colour, Farrow and Ball’s Borrowed Light. Borrowed Light is a very light blue; like a Canaletto sky.
