This Wikipedia article explains some thermochromic principles:

Without knowing what you PHD thesis deals with, it is hard to make any further suggestions except to say that a lot of the technology is very recent and has only become available because of microengineering. If there were a simple and easily available chemical or organism which could reliably show a colour change at a certain temperature, then I am sure that the fact would have be exploited long ago.

Like organism it it known the skin,the colour change in red.Like chemical:HgI with CuI change the red colour at 70Celsius[32+1.8*70]Fahrenheiht.Also AgI and HgI from yelow became red-orange at 40C,the processes are reversible.Also,are thermocolours between 30 and 650C for industry..At high temperatures the metals are red at 700C,open yelow at1100C and white over1500C.Also others.

Some cobalt compounds change colour reversibly with temperature. A good example is cobalt(II) thiocyanate which is blue when heated (less than boiling point of water) and crimson when cooled.
What temperature range did you want to cover?

Humans change colour (in the sun) and are definately temperature sesitive!

Yes, Pigs
When you heat them up they turn pink and become bacon
Also you spelt temperature incorrectly

Erm thsi may not be right so look it up but I think Carbon is, and possibly potassium permanganate (spelling??)
Good luck!!

oh there's a lot of them. if you're trying to find one to use as an indicator try scifinder property search. other than that i can't help unless i know what your thesis is supposed to be on
