Here's a brief overview:

Early Years (1951-1971):

The Sun Devils initially wore simple gold helmets with a white "ASU" decal on the side.

Variations included a maroon stripe down the center of the helmet and a white "Sun Devils" decal.

These early designs were primarily focused on school colors and lacked any mascots or logos.

Sparky's Introduction and Experimentation (1972-2004):
The iconic Sparky the Sun Devil mascot was introduced on the helmet in 1972, initially as a small decal on the back.

Throughout the years, Sparky's size and position on the helmet varied, including full-face designs, profile versions, and Sparky holding footballs.

The program experimented with various colors, including maroon stripes, black facemasks, and even an all-chrome design in 1980.

Stability and Refinement (2005-Present):

In 2005, the Sun Devils adopted a more consistent approach, settling on the classic gold helmet with a larger, full-face Sparky decal on the side.

The maroon facemask became a permanent fixture, and variations have included chrome accents, alternate Sparky logos, and special edition designs for specific games.

This consistent design has fostered a stronger visual identity for the program and has become instantly recognizable with ASU football.

Recent Innovations and Future Possibilities (2019-Present):

In 2019, the program introduced a "color-shifting" maroon helmet, adding a new dimension to their helmet designs.

The Sun Devils experimented with a white helmet featuring Sparky's face in 2023, marking the first time Sparky appeared on a non-gold helmet.

These recent innovations suggest the program is open to exploring new design possibilities while maintaining the core elements of its identity.
