These dice glow due to the kind of plastic used. In the light these dice typically look like a sort of light yellow-green, though some do come in different colors, in which case we’ll also have a picture of what they look like in the light (you can find this under the “additional images” tab on the product page. These dice are “charged” by sitting in the light for a time, the brighter the better. They will then glow brightly in the darkness, and the intensity of the glow will slowly fade over time.

Typically these dice will have numbers inked on that will appear dark against the glowing surface of the dice regardless of the color of the numbering, but there are also glow in the dark dice where only the spots of the dice are made from glow material, in which case the dice are as dark as anything else without light, and you just get the glowing spots.

The patterns and numbers on the dice can emit light of different colors, and the color depends on the color of the luminescent pigment. Add a proper amount of luminous pigment to the ink and mix it to make luminous ink. Printing this kind of ink on the surface of the dice adds a different entertainment effect during the game.

Under dim lighting, it can show terrifying science fiction or future visual effects without resorting to external factors.
