What are Smart Pigments?

Smart pigments:

 

To create smart temperature-sensitive inks, paints and coatings.

Some substances respond to temperature changes by changing colour.

They absorb heat (infra-red radiation) and give out light. 

We can use these thermochromic pigments to colour.

They are useful wherever you need a visual warning of a change in temperature.
