Hot or cold?

I find it very interesting and advanced to see soda machines here in Japan like this. If you look closely at the bottom row you will see that the labels are all red. If you look at the other two labels you will see that they are blue. If you haven't guessed it already, this machine sells drinks that come out cold and drinks that come out hot. I haven't tried any of them yet, but I think that it is pretty dang cool that they are able to do this. I also ran into a cooler/heater at a store that had hot drinks on one level and cold drinks on the other and really the hot drinks were hot and the cold drinks were cold.
