How many hours can you spend choosing colours to paint your new walls?

Well I think I must have clocked up at least 6 so far perusing the brochures while sat in bed spread over 3 different sessions. I think I have decided now and it's only 2 colours for 2 rooms I'm buying after all that mental effort. Needless to say you'll turn up and think 6 hours very well spent (or not).
