It's not just a matter of imagination to create a colorful palette on something as sweet as chocolate

This is the legendary structural color, which does not depend on pigments or other additives.

To make the iridescent chocolate, a product developer speculates, the researchers created a nanotech chocolate mold, using electron beam lithography to etch lines about 100 nanometers wide on a glass or silicon mold.

This structural color isn't the first time it's been seen on food, it's sometimes seen on cooked beef as well
