👉 Photochromography is a technology that allows materials to change color based on light intensity. In other words, it's like using a flashlight to see different colors in different conditions. For example, if you shine a bright light into a dark room, you'll see only the blue or green colors because there's no way for the material to absorb or reflect any other colors. But when you shine a lighter light into a brightly lit room, you'll see more colors due to the photochromic properties
