Thermochromic Liquid Crystals(LCs) are highly temperature sensitive, changing through many colors. Starting as black below their temperature range, they go through the colors of a rainbow as temperature is increased finally changing back to black again when above their temperature range. LCs are reversible and can be used repeatedly.

The technology is like that used in TV and Watch Displays. However, instead of reacting to electrical impulses, they respond to fluctuations in temperature. They can be formulated to react to temperatures between -30°C (-22°F) and 120°C (248°F) and react to changes in temperature as small as 0.1°C (0.2°F). They are also accurate up to +/- 1°C, and if stored and used correctly, they will remain functional for many years.
