Hi. Am trying to find a wall colour to go with our light grey kitchen units. The left colour is Ammonite & the right is Strong White. The latter gives more of a contrast but do you think it is too similar a colour to the units? It's so hard when the colours change so much in different lights. The worktop will be white quartz (maybe marbly). Any help much appreciated as decorator starting tomorrow! BTW in the pics with 3 colour the right is Blackened which I'm not keen on. Thanks.
