Hi, I used Farrow and Ball colour consultancy service (
http://www.farrow-ball.com/colour-consu ... cp-content) a few months ago. I highly recommend it.
We covered 5 rooms in an hour, which cost £175. This gave me the confidence to pick the colours for the other rooms on my own and even to make a few changes on the colours we had initially picked together.
Using their service doesn't mean you have to use their paint either. You can use their report to order their paint, or just use it as guidance to select your colour scheme.
I had prepared pictures of rooms I liked from magazines, as well as pictures of our furniture before the appointment, and it made the process very quick and easy. I also got quite a few tips out of it.
We haven't finished decorating yet, but I'm confident I'll like the result AND it saved me hours of surfing the web and flicking through books and magazines to make up my mind.
