SquidLondon is a young innovative company that experiments with color-changing products. Their most notable concept, a water-reactive umbrella that uses hydrochromic inks that change the white part of the umbrella to color when wet. How does it work? Basically (from what I learned from Wikipedia) it works the same way similar existing materials usually react to heat or UV light, but instead, this ink changes color in contact with water.
