Blush Radiator is Blue When Cold, Red When Warm: Beating Hearth

 |  |  |  |  |  October 18, 2013

A couple of weeks ago we saw a car that changes color when it’s wet, thanks to a coating of thermochromic paint. Icelandic designer Thorunn Arnadottir used the same kind of paint to make a radiator that, together with its twisting tubes, makes it appear organic. She calls it Blush, and it’s easy to see why.


Blush clearly mimics the appearance of a capillary, the smallest type of blood vessels. They facilitate the exchange of nutrients as well as waste materials and are often depicted in illustrations as having blue and red halves. Thorunn said, “Blush is a very important organ of the house. Regulates the temperature and keeps it warm and alive.”


I’d love to see more appliances that change color depending on their state. Perhaps a fridge that turns gray when there’s spoiled food inside. Or a bathroom door that turns brown to tell you that someone just dropped bombs inside.
