A new Chameleon paint which allows people to change the colour of their cars, phone cases and trainers as many times as they want has been created by MIT researchers. The reprogrammable ink changes the colour of an object after it is exposed to ultraviolet and visible light sources at different wave lengths. A team from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) designed the system, which has been dubbed'PhotoChromeleon'. One researcher said the tool will allow users to personalise their appearance and belongings multiple times in a variety of styles and colours. The chameleon paint was designed by a team from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) which has been dubbed'PhotoChromeleon' They created the ink by mixing cyan, magenta, and yellow photochromic dyes into a single sprayable solution.
