The cool rainbow thing on NFL helmets is called the prismatic visor decal or prism decal. It’s part of the NFL’s ongoing efforts to show support for diversity, equity, and inclusion. These decals feature a spectrum of colors resembling a rainbow and are usually displayed on the back of helmets during specific awareness campaigns, such as the NFL’s “Inspire Change” initiative.
The prismatic effect adds a vibrant and eye-catching element to the design, symbolizing unity and inclusivity. These decals have become a significant statement of the NFL’s commitment to promoting social justice and equality within the sport and beyond.
