Scientists in Switzerland have found a way to make chocolate look colorful without adding additional ingredients.
Switzerland's Federal Institute of Technology announced today that researchers have discovered a method for imprinting a special structure on the surface of chocolate that makes it sparkle and "sparkle like a rainbow."
The institute says the process mimics the effect of a chameleon's skin changing color.
The announcement says that "rainbow chocolate" is ready for industrial production, which scientists are already negotiating with large candy manufacturers.
