The company teased the device ahead of its August 11 launch in China. This follows the earlier reveal of the Cabernet Red variant for the K100 Pro Max.
Glow-in-the-Dark Design
The Glowing Firefly color has a fluorescent green finish that changes appearance depending on lighting.
Redmi placed a special luminescent material between the glass back and the green ink layer.
After absorbing light from a flashlight or other bright source, the back panel glows in the dark. Users can create temporary glowing patterns on it.

During the day, the phone has a translucent green finish. The glow effect becomes visible in low-light conditions.
The metal frame and camera island are also matched with the same green color. This gives the phone a more uniform look.
In addition to Glowing Firefly, the K100 Pro will also be available in a silver edition.

Redmi reiterated that the K100 Pro will feature a 6.59-inch flat OLED display using new M11 light-emitting material.
