I'm fascinated by cultural nuances like this. I really, really wish there was a website where you could look up things like this based on culture. I don't know how one would start to gather the data for a site like that.
You can start with something more concrete, like color names, ie where stop the yellow and start the red on a rainbow. But in fact, this is just a matter of definition, and is not that interesting. I would find more interesting to diff daily life things, like fridge content, number of close relatives, hygienic habits.
