Decorating decisions...kitchen cabinets...

Just when I think I have decided upon a paint colour for my kitchen cabinets I change my mind again! I have got just about every paint card from all the 'posh paint' companies, and I have tried out so many colours! The 'Rita Says' sample pot I ordered, disappointingly turned out to match the computer screen sample colour and not the colour chart, being pale blue instead of the grey I wanted! At the moment I am torn between two 'Farrow & Ball' greys-'Blackened' and 'Cornforth White'.
I think I prefer the 'Cornforth White' but that could all change when I buy the sample pot! We have the 'Blackened' in our bathroom, so I think I'd like a different colour in the kitchen.....
Another good website to browse through is 'Posh Paints'. They stock all the designer posh paint brands and group them into colour families which is really useful if you are trying to compare different brands versions of the same colour!
