Coloring umbrellas - rain that is not boring to you
British design studio Squid London offers some good mood on a rainy day. Specifically, the British offer to paint umbrellas with special paints that change color if they get water. The more the fabric gets wet, the brighter the pattern appears. The principle here is exactly the same as in children's books of water-colorings (when pictures change color from water). With the only exception that the ink that is used in Squid London umbrellas restores color after drying.
