Here is a lesson to others choosing paint colours. Dulux 'buff' and Dulux 'buff it' are 2 totally different colours. We now know this. I suspect 'buff' is an old colour as it doesn't come up on the dulux web site search as a current colour - in-fact it directs you to 'buff it' which is the colour we wanted. Despite this the painter managed to find the wrong one.
For the record the colour in the photo is Dulux 'buff' and we hate it.
