IBJJF rules allow only three gi colors: white, royal blue, and black. Jacket and pants must match and be one solid color. No gray, no navy, no camo, no bi-colored gis. Local tournaments may differ, so always confirm with the specific event’s rulebook before you buy.
- IBJJF approves only 3 gi colors: white, royal blue, and black.
- Jacket and pants must match — mixing approved colors still counts as bi-colored.
- Navy, gray, green, camo, pink, and red all fail IBJJF inspection.
You Spent Good Money on That Gi. Then They Turned You Away.
Picture this. You drove two hours to the tournament. Entry fee paid. Three months of training behind you. You walk up to the table — and the volunteer looks at your gi, then back at you, and shakes their head.
“Sorry. That color isn’t approved.”
It happens every single weekend at IBJJF events. Not to careless people. To people who trained hard, paid full price for a gi, and trusted the wrong source. The rules aren’t vague — but the marketing sure can be.
Here’s the one rule most BJJ beginners get wrong: “competition-ready” doesn’t mean IBJJF-legal. Those are two different things.
The 3 IBJJF Legal Gi Colors
The IBJJF keeps it simple. Three colors. Full stop.
| Gi Color | IBJJF Legal? | Notes |
|---|---|---|
| White | ✓ Yes | Most common at competitions |
| Royal Blue | ✓ Yes | Must be true royal blue — not navy |
| Black | ✓ Yes | Popular at higher belt levels |
| Navy Blue | ✗ No | Too dark — not royal blue |
| Gray | ✗ No | Very common mistake |
| Green | ✗ No | Not approved, any shade |
| Camo | ✗ No | Counts as bi-colored — auto rejection |
| Pink | ✗ No | Not approved |
| Red | ✗ No | Not approved |
| Bi-color (any mix) | ✗ No | Top and bottom must match, solid |
The rule also covers your full gi set — jacket AND pants must be the same approved color. White top with black pants? That’s bi-colored. That’s a DQ.
Why Navy Gets Confused with Royal Blue
This one trips people up constantly. A lot of gis are sold as “blue” and they’re actually navy. Navy is dark — almost black in bad lighting. Royal blue is bright, medium-toned, saturated blue. Think the blue in the American flag, not a police uniform.
Under tournament lighting, officials catch the difference immediately. They’ve seen every shade of “but it’s basically blue.” They’re not going to let it slide.
When shopping, look for “IBJJF approved” or “royal blue” in the listing. If the description says “navy,” “midnight,” or “dark blue” — walk away. Stylso’s blue gi is royal blue, not navy. That distinction matters on comp day.
The 4 Rules to Know Before You Register
- Only white, royal blue, or black. Not navy. Not light blue. Not charcoal. The three real colors.
- Jacket and pants must match. Both pieces. Same color. Same shade.
- One solid color only. No bi-colored gis. No color panels. No contrast stitching that reads as a second color.
- Check your specific event’s rulebook. Local and affiliate tournaments sometimes run different rules. Always verify before you register.
Which Stylso Gi Colors Are IBJJF Legal?
Stylso makes gis in white, black, blue, navy, and green. Here’s the straight answer for competition:
| Stylso Color | IBJJF Competition? |
|---|---|
| White | ✓ Legal |
| Black | ✓ Legal |
| Blue (royal blue) | ✓ Legal |
| Navy | ✗ Not IBJJF legal |
| Green | ✗ Not IBJJF legal |
For IBJJF competition, stick to white, black, or blue. If you’re training recreationally or competing at a local open with relaxed rules, navy and green are fine for that.
Which Color Should You Actually Buy?
Here’s the honest take.
White if you’re a beginner or buying your first comp gi. It’s the most traditional, the safest bet at any event, and it’s easy to spot-clean between wears.
Black if you want something that hides mat grime and looks sharp at higher-level events. A lot of purple, brown, and black belts compete in black. Clean, no-fuss.
Royal blue if you want to stand out on the mat in a legitimate way. Fully legal, photographs well, and easy to distinguish from the navy trap.
Before you order, get your size right first. BJJ gi sizing isn’t like regular clothing — an A2 in one brand can fit very differently from another. How to measure for a BJJ gi will save you a return.
Not sure which weave matters for competition weight? The difference between fabrics affects how heavy your gi feels at weigh-in. Pearl weave vs gold weave breaks it down fast.
Keep Your Gi Competition-Ready: A Real Coaching Tip
Here’s what most buyers skip: washing your gi wrong kills the color faster than anything else.
White gis yellow with hot water and harsh detergent. Black gis fade to gray over time. Royal blue gis can go dull and start reading like navy after too many hot washes. A faded gi can fail inspection just as fast as the wrong color.
Simple fix: cold water, gentle detergent, air dry. For the full breakdown on keeping your gi from losing shape or color, how to stop a gi from shrinking covers exactly what settings to use.
How BJJ Compares to Judo and Wrestling on Uniform Rules
Here’s a real cross-discipline insight: BJJ is stricter about colors than judo in some ways, and far looser about patches than wrestling.
Judo (IJF rules): Competitors must wear one white and one blue gi — the seeding draw determines which color you wear. You need both at international events.
Wrestling (folkstyle/freestyle): No gi. Color rules apply to singlets, which are typically event-assigned.
BJJ (IBJJF rules): Three approved colors, solid only, matching top and bottom. You choose — within those three. Patches and embroidery are allowed but regulated by size and placement rules.
If you cross-train, don’t assume the color rules transfer. Each governing body sets its own standards. Always check.
The Night-Before Drill
Build this into your comp prep every single time:
- Pull your gi out the night before — not the morning of.
- Hold it up in good light — does it clearly read as white, royal blue, or black?
- Lay jacket and pants side by side — do they match exactly?
- Check for patches or contrast panels that could flag you at inspection.
- Pack it, zip the bag — done. No morning scramble.
Five minutes the night before beats an hour of panic on comp morning.

FAQ: IBJJF Gi Color Rules
What are the IBJJF legal gi colors?
IBJJF only allows three gi colors: white, royal blue, and black. Your jacket and pants must match and be a single solid color. No bi-colored or multi-colored gis are permitted at IBJJF events.
Is navy blue allowed at IBJJF competitions?
No. Navy blue is not IBJJF approved. Only royal blue — a medium-toned, saturated blue — is on the approved list. Navy looks similar in photos but is noticeably darker under tournament lighting, and officials are trained to spot the difference.
Can I wear a white jacket with black pants at an IBJJF event?
No. Mixing colors — even approved ones — counts as a bi-colored gi and is banned. Your jacket and pants must be the same color and come from the same matching set.
What happens if I show up to an IBJJF event in an illegal gi color?
You’ll be turned away at the inspection table and won’t be allowed to compete. Some events may give you a short window to find a legal gi, but that’s not guaranteed. Always verify your gi color before the event.
Do local tournaments follow the same gi color rules as IBJJF?
Not always. Local and regional events often have their own rules and may allow a wider range of colors. Always check the specific rulebook for your event — don’t assume what’s legal at one tournament applies to another.
What is the safest gi color to buy for any BJJ competition?
White is the safest choice for any BJJ competition. It’s approved at IBJJF events and accepted at virtually every local tournament. If you can only own one competition gi, white gives you maximum flexibility across all rulebooks.
You put in the work. Don’t let a gi color be the thing that keeps you off the mat. Buy legal, wash it right, and go compete.
