Every woman would like to try new colors and collect a variety of lipsticks to meet the different makeup needs, which causes the waste of package/resources and money.
COLORFUL LIP has a color sensor on the bottom, so when you put it close to something, it can pick up the color automatically. It finishes when the LED light belt is on. Then the RGB mixing box inside will use natural food colorants to make the color you want. Finally, when you spin out the lipstick, you will get the color on the top. Only the top is colored so that you can try another color every soon.
