Q: Do you know what the autoignition temperature of paper is? 
A: 451� F
Fahrenheit is a vivid reddish-orange color that is reminiscent of the fire engine that Guy Montag may have ridden. 
Note: For the most vibrant results, please use Fahrenheit over a similarly colored basecoat, such as orange. Fahrenheit may also be used over other basecoats such as white or black for different effects.
