It looks like a glitch in a video game. You’re flipping through channels on a Saturday afternoon, and suddenly, your screen is screaming neon cobalt. It’s jarring. It’s beautiful. To some traditionalists, it’s an absolute eyesore. But for anyone who knows anything about college football, that Boise State football field blue is the ultimate symbol of a program that refused to play by the rules.
They call it the "Smurf Turf." Honestly, the name fits.
Back in 1986, Boise State’s athletic director, Gene Bleymaier, had a problem. The school needed to replace the worn-out green carpet in Albertsons Stadium (then Bronco Stadium). The cost was around $750,000—a massive chunk of change for a Big Sky school at the time. Bleymaier figured if they were going to spend three-quarters of a million dollars on a new floor, people should at least notice. He didn't want to just be another school with a green field. He wanted to be the school with the blue field.
The idea was polarizing. Some folks thought it was a gimmick that would make the program a laughingstock. Instead, it became the greatest marketing masterstroke in the history of the NCAA.
Why The Blue Turf Actually Happened
You’ve probably heard the rumors. People say the blue field was installed to confuse ducks flying overhead so they'd crash into it thinking it was a lake. That’s a total myth, by the way. No ducks were harmed in the making of this stadium. The reality is much more pragmatic: money and branding.
Bleymaier realized that Boise was a small market. To get recruits to look at Idaho, and to get TV networks to care about a mid-major program, they needed a hook. When the blue turf debuted on September 13, 1986, against Humboldt State, the college football world shifted.
It wasn't just about the color. It was about the psychology.
Opposing teams hate it. They talk about how the glare off the blue blades makes it hard to track the ball. They complain that Boise State players "disappear" into the turf when they wear their all-blue uniforms. While the NCAA eventually passed a rule (often jokingly called the "Boise State Rule") requiring teams to have contrasting jersey colors, the advantage remains. It's a mental hurdle before the ball is even snapped.

The Science and Maintenance of the Blue
This isn't just blue spray paint on grass. We’re talking about a highly engineered synthetic surface. The current iteration is a FieldTurf product that uses a specific shade of "Royal Blue" polyethylene fibers.
Maintenance is a beast.
Unlike natural grass, you don't mow it, but you do have to "groom" it. This involves using a specialized tractor with a brush attachment to keep the rubber infill—those tiny black pellets—evenly distributed. If you don't groom it, the blue blades lay flat, the field gets "fast" (slick), and the color looks dull under the stadium lights.
Sunlight is the enemy. Over time, UV rays try to bleach that iconic cobalt into a sad, dusty periwinkle. Because of this, the school has to replace the entire surface every 7 to 10 years. The most recent installation happened in 2019, keeping that vibrant pop that looks so crisp on 4K broadcasts.
The "Blue Turf" Trademark and Why Nobody Else Has One
Ever wonder why you don't see a "Grape Ape" purple field at LSU or a bright red "Blood Turf" at Nebraska?
It's because Boise State owns the rights.
In 2011, Boise State secured a federal trademark for "non-traditional turf colors." Basically, if any high school or college in the United States wants to install a football field that isn't green, they technically have to ask the Broncos for permission.

It sounds like a "tough guy" move, but Boise State is actually pretty cool about it. They usually grant a "royalty-free license" to schools that want to go wild with their colors, provided those schools acknowledge Boise State as the innovator. You’ll see this at Eastern Washington University (which has a bright red field) and Coastal Carolina (which went with "teal" or "surf turf"). But make no mistake: Boise State is the gatekeeper of the colorful gridiron.
Does the Blue Actually Help Them Win?
Let’s look at the numbers because they’re honestly staggering. Since the blue turf was installed in '86, Boise State has maintained one of the highest home winning percentages in all of college football.
Is it the turf? Or is it the altitude? Or is it just that Boise State consistently out-coaches their opponents?
It’s probably a cocktail of all three. But you can't deny the "Blue Magic." There’s an intimidation factor. When a Power 5 team travels to the Treasure Valley, they aren't just playing a game; they’re entering a blue-tinted fever dream. The crowd is draped in blue. The end zones are blue. The mountains in the distance are blue. It creates a claustrophobic atmosphere for visitors.
Common Misconceptions and Legal Battles
One thing people get wrong all the time is the "Invisibility" argument. In 2011, the Mountain West Conference briefly banned Boise State from wearing their all-blue uniforms at home for televised games because coaches complained it was an unfair advantage.
The ban didn't last long.
The school fought back, arguing that plenty of teams wear green jerseys on green grass without anyone batting an eye. Eventually, the conference relented. Today, the Broncos wear their blue-on-blue with pride, and it remains one of the most iconic "looks" in the sport.

Then there’s the cost. People think the blue turf is more expensive than green. Not really. The manufacturing process for the blue plastic fibers is virtually identical to the green ones. The "cost" is mostly in the branding and the trademark enforcement.
Visiting Albertsons Stadium
If you’re a fan of the game, you’ve gotta see it in person. Photos don't do justice to how loud the color is under a Saturday night sky. The stadium itself has expanded over the years to hold over 36,000 fans, but it still feels intimate.
When you walk into the Hall of Fame at the stadium, you can see a piece of the original 1986 turf. It feels like a relic. It’s rougher, more like a cheap rug than the modern "grass-like" blades they use now. It reminds you that this whole thing started as a scrappy, budget-conscious gamble.
How the Blue Turf Changed College Sports Branding
Before Boise State, college football was a sea of emerald green. Tradition was king. You didn't mess with the field.
Boise State proved that you could build a national brand from a "flyover" state by leaning into your weirdness. They didn't try to be Michigan or Alabama. They leaned into being different. Now, we see Oregon with their 400 different uniform combinations and Maryland with their flag-patterned helmets. All of that "look at me" branding in modern sports owes a massive debt to a guy in Idaho who decided green was boring.
What To Watch For Next Season
If you’re tracking the Broncos, keep an eye on how the field looks during day games versus night games.
- Day Games: The blue can appear almost neon, and the shadows from the stands create high-contrast zones that make it difficult for quarterbacks to see safeties rotating late.
- Night Games: Under the LED lights, the turf takes on a deeper, navy hue that feels much more "classic football."
The school is constantly evaluating the "speed" of the turf. Modern players want a surface that allows for quick cuts without the "grab" that causes ACL tears. Boise State works closely with turf engineers to ensure their blue carpet isn't just a gimmick, but a high-performance athletic surface.
Actionable Takeaways for Fans and Travelers
If you are planning a trip to see the Boise State football field blue for yourself, or if you're just a student of the game, here’s how to do it right:
- Check the Schedule for "Blue Out" Games: The atmosphere is 10x more intense when the entire stadium is coordinated in blue. It’s a literal ocean of color.
- Take the Tour: You can actually get onto the field during stadium tours. Touching the turf is a bucket-list item for many "turf nerds."
- Respect the Trademark: If you’re a high school AD looking to install a "Cool Gray" field, call Boise State’s legal department first. They’re friendly, but they protect their brand fiercely.
- Look for the Brono Logo: The center-field logo is massive. It’s a great way to judge the scale of the field when you're sitting in the upper decks.
- Watch the Warm-ups: Watch how the visiting kickers handle the blue. Many struggle with depth perception because the blue doesn't provide the same visual cues as green grass.
The blue turf isn't going anywhere. It’s survived conference changes, coaching carousels, and the transition from the BCS to the Playoffs. It’s more than just a surface; it’s the heartbeat of a city that loves its "Blue Turf" as much as any blue-blood program loves its traditions. Whether you love it or hate it, you can't ignore it. And in the world of sports, that's the ultimate victory.
