I know several people who proudly proclaim they have a 'blue room' in their house. By which they mean a room that is painted blue.
'Course you can stay over! You can go in the blue room'
That kind of thing.
It even stretches to work: at the other end of my corridor there's 'the blue room', spoken of in hushed, reverential tones by members of HR.
However, no one ever seems to make such a fuss about their 'beige room' or 'puke-yellow room'.
What's the deal with this, eh?
