Jelly Belly jelly beans under normal light ...................... and the same under ultraviolet light


Many common products, such as crayons, markers, paper and even T-shirts...

...are impregnated with dyes that absorb naturally occurring ultraviolet light and re-emit it in intense colors to make the colors appear more brilliant and give whites a brighter, whiter look. When viewed under artificial ultraviolet light sources in a dark room, these fluorescent dyes glow with brilliant intensity.


The food industry uses dozens of food grade, edible fluorescent dyes to enhance the colors of their products. The Jelly Belly company uses them in their jelly beans. Additionally, many normal coloring agents also exhibit fluorescent properties. The result is that many Jelly Belly jelly beans look completely different under ultraviolet light than they do under normal light. Here are a few examples:

Cappuccino turns bluish green. AW Root Beer exhibits a similar color change.


Strawberry daiquiri goes becomes a brilliant hot pink.

Plum Jelly Bellies are my favorites not only because they taste so good but because they display one of the most extreme color changes.



Watermelon's color changes reflects a real watermelon: green on the outside and red on the inside.


Pina colada goes from yellow to greenish blue.


Mixed berry smoothie turns an electric hot pink. Beautiful!
Look carefully and you can see two eyes, a small nose and the hint of a mouth.
I think I've discovered the first Jelly Belly emoji!
