Homebrew PCBs

Saw some videos on what looks like an LCD type of chemical that changes 
color with temperature.
Im looking to experiment with some chemicals that change color with 
temperature, sort of like
a thermometer read by color instead of numbers.

Any ideas or sugguestions out there? I remember a couple of people here 
seemed very good with
knowledge of chemicals. I happened to skip chemistry class in high school - 
hehe.
