<p>I found a supplier of raw thermochromic pigment active in the temperature range you are looking for. But to make it into paint you would have to add binder yourself.</p>

<p>Has different thermochromic pigments active in the ranges -5C to 78C</p>

<p>Be sure to specify the temperature range you are interested in.</p>

<p>Is there any kind of thermochromic material and/or paint that is capable of changing its color in the range from 4-8°C (39-46°F)? I'm trying to paint a glass bottle and want a visual aid for its temperature.</p>

It's not strictly thermochromic but LCD thermometers can cover this range so maybe there's something you can modify/attach ([example](http://www.thermometersdirect.co.uk/lcd-thermometer-tempstrip-3degc-to--13degc.html))

Back in the 80s, you used to be able to get these thermometers that were a plastic card, and the ink would change on it depending on the temperature, and tell you what temperature they were.  It seems to be called a [liquid crystal thermometer](https://en.wikipedia.org/wiki/Liquid_crystal_thermometer).  I don't know if it's possible to get sensitivity at the temperatures you're looking for, but if they make ones for fridges, I would assume so.  This might also be the tech behind the winter gloves that would change when they got cold.

Currently [some beers](http://blitzlebels.com/super-cool-labels/) have labels with elements that appear or change color around that temperature range ("perfect for drinking")

Is there any kind of thermochromic material and/or paint that is capable of changing its color in the range from 4-8°C (39-46°F)? I'm trying to paint a glass bottle and want a visual aid for its temperature.
