The Rainbow Thermal Color Palette comes in multiple options: The first is typically standard ‘Rainbow’ or ‘Rainbow 1’. This thermal color palette is simplistic with warmer colors representing warmer thermal signatures and cooler colors representing colder thermal signatures. The second option is often called ‘Rainbow HC’ or ‘Rainbow 2’. This is the same Rainbow Thermal Color Palette but with more high contrast. What this does is allow for more contrast to be added to the thermal imaging creating additional detail compared to other thermal color palettes making it easier to spot subtle temperature differences.
Although the rainbow thermal color palette is not often used in real world events it is still a useful thermal color palette imaging when needing to detect heat signatures and slight temperature differences in low contrast areas. The rainbow thermal color palette is often seen in movies and video games, some of the most popular being in Tom Clancy style first person shooter games.
Hiding from thermal detection when the thermal imaging technology is set to Rainbow and/or Rainbow HC can be very tricky. Due to the subtle temperature changes Rainbow or Rainbow 1 reduces the warm color ratio and increases the cold color ratio for higher temperature targets. This simultaneity better shows the detail of cooler targets. Rainbow HC or Rainbow 2 reduces the color transition making the warm and cold colors moderately proportioned which in turn displays the details of high and low temperature targets at the same time.
Similar to other thermal imaging color palettes the best option to hide from thermal detection is utilizing specific tools and equipment such as the Beez Combat Systems Predator Ghillie™ SPECTRALFLAGE BLANKET. Hanging the SPECTRALFLAGE BLANKET like a hide and creating a distance between the end user and the equipment will greatly reduce thermal detection thus allowing the end user to successfully mask their thermal signature.
