This Mac advert kinda sums it up really - how totally drool worthy?
It seems to work best with strong saturated colour. Would you be brave enough to do this in a room?
I don't think it works as well with neutral walls (or maybe its that rug - like it, but not here in this setting) whereas the strong colour give instant sex appeal and screams glamour.
I really like this cobalt colour (below) with the pops of yellow. Not so keen on the ceiling colour though or the rug.
