Paint Colours

[chrispriddyuk]

Hi all.
We wrote to Dulux with photos of our terrace of houses and asked for colour recommendations, they sent us some and we picked one of their choices.
I have since lost the letter and all contact details for who helped us.

However our local dulux centre tells me that the colour 'Linnet White" isnt able to be mixed into Weathershield exterior paint. Which seems silly seen as they suggested it.

My question is..... is there a better way of finding a similar or best close matching colour from any company other than getting hold of all their colour charts and doing it by eye.

Thanks

Chris
