Interesting transformation of optical color pigments in toy design

The toy market has become more interesting due to the application of optical color pigments. A new type of children's toy uses optical color pigments to make the shell. During the play process, as the child fiddles with it and the light changes, the color of the toy will continue to change, from red to green, and then to blue and other colors. This magical color-changing effect not only attracts children's attention and stimulates their curiosity and desire to explore, but also provides new elements for the innovation and fun of toy design, making the toy more attractive and interactive.
