According to nutritionists, naturally color-vibrant foods serve an important role in keeping you healthy and even reducing cancer risks. I have created an optical nutrition indicator to help show users which fruits and vegetables are part of a colorful, healthy diet easily and interestingly. The indicator can sense colors of the vegetables and fruits eaten and project the colors onto the wall in means of rainbow-like light. The indicator includes two separate parts, the projector and the cutting board. The cutting board can hang above the projector which can be fixed on the wall.
