True, but it really isn't a scale of "temperature". It's a scale of the light emitted when a black body is heated to a certain temperature, in Kelvin. So while the scale may be counter intuitive strictly from a numbers perspective, what light do you find cooler, blue, or red?
Since blue is perceived by most as cooler, even though the light emitted by a very hot object is blue, the scale interprets it as cooler.
Oh and I've read a few articles on negative Kelvin that were pretty interesting. They stated that there is actually a colder temperature than absolute zero. Way off track, but an interesting read if you're into geeky things like that :D
