A few days ago we found out that classical color scheme for termal map rised some too many questions. So, here are two options (from the left to the right => from the hottest to the coldest)
1. Realistic option. White color - the hottest, dark blue - coldest. This color set is used in real life (for termal imager, thermovision sights and even in weather forecasts).
or
2. Casual option. Where red is hottest and black-blue - the coldest, with yellow in middle.
What option is the best for U?
