The "colorful" IR is simply a palette map at the end of the shader. Once 
you have "intensity" then you map that to the S texture coordinate of a 
color ramp texture, and out comes the display color. Depending on which 
piece of hardware you want to emulate, typically you apply bloom BEFORE 
the palettization, which means you need some render target ping-pong-ing.
