I am buying a house with DP which is quite dated throughout. We have got plans to create an extension which would probably affect most of the rooms downstairs and might not happen for a few years. In the meantime the plan was to paint the whole house white, but now I am scared that it will be cold and am toying with the idea of painting the whole house light grey. Not shades of grey, all exactly the same shade which I am sure will look subtly different in different lights and I was hoping to accent with different colours in different rooms. Is this a crazy idea? Google suggests that this is not the done thing but not sure if we are capable of choosing one colour let alone several!
