It’s often the simplest ideas that are the coolest, and the Hansacanyon is definitely one of those ideas.
Human’s use their senses for everything, and we frequently operate better when we’re using multiple senses.
In the case of being able to tell the temperature of water, we typically rely only upon touch, and sometimes we can get burned, literally.
Germany’s Hansa with its innovative Hansacanyon also allows us to use our sight, by adding LEDs to the faucet that are illuminated as a function of water temperature so you are able to see whether the water is a warm hot or cool blue.
And utilizing such lighting makes the Hansacanyon not only practically, but the ambient lighting is also highly aesthetic.
