Yeah pretty much.

>or "what would infra red look like if it had a colour?"

whatever our brains decide it should look like. Colour isn't an objective quantity intrinsic to each wavelength. It is a figment of our brains.

One interesting thing about human colour perception is that in terms of responsiveness to certain wavelenghts, our colour cones are not spread out evenly at all. Our Red and Green cones pick up wavelengths which are practically beside each other whereas blue is way off at the other side. If you look at all the visible wavelengths you will not see much subjective difference between different shades of "blue" which are as different from each other scientifically as red is from yellow!

Aparently the reason for this is that colour vision evolved when our ancestors lived in trees to help them find good fruit among the leaves (telling red, yellow from green was important). Blue evolutionarily was more of a background colour (water, sky etc.).

Weird, eh?
