Apple Watch owners will be able to change the band color directly on the smart watch according to their outfit combinations or their current mood. This will be possible by using materials with electrochromic properties in the band.
Change color by notification
Next-generation cords will be able to change color or pattern in response to applied voltage. In addition, it will turn into a different color when notifications are received from any application. Apple also has the idea to display text messages on the lanyard.
Apple Watches can currently be customized with replaceable bands made from materials such as silicone, steel, and leather. It seems that in the future we will have the opportunity to customize the look of the smartwatch through a single band.
