> Though finelinebob was saying that the colour spectrum is inverted from how it is in physics (red should be low activity because it is... low frequency?)
Red photons are lower in energy than violet photons.
The "infra" in infrared means "below". The "ultra" in ultraviolet means "beyond". Terminology, again, based on energy.
If "hot spots" on a scan are a measurement of high levels of energy, a scientifically "honest" mapping would make violet hot and red cold ... but the culturally honest mapping of making red "hot" may make scans easier to interpret, since pre-meds never take physics seriously.
