Is it possible to heat one or two molecules only so that they produce a distinct colour? Like heating one molecule so that it's blue and the next so that it's purple... or would it have to be different gases?

Hi P-man,
Thats a really good question. This area is called Thermochromic chemistry.
A link with some more information about this area is
http://en.wikipedia.org/wiki/Thermochromics
. It is commonly used in paper, paints and ink.
I am not sure if Television tubes (the phosphorous coating) could be considered Thermochromic, but it may. The resolution on a Television screen would have differences in colours by very small distances.
I hope this helps,
Eugene
