What color is your Locator Bar marker?
Minecraft gives every player a marker color derived from their UUID, and never shows it to you. Type a Java username or UUID to see it.
Nothing to show yet
Enter a username or UUID above and the exact marker color appears here.
How this color is decided
Java Edition takes UUID.hashCode(), keeps the low three bytes as red, green and blue, then shades every channel to 90% before drawing the marker. Same UUID, same color, every single world.
Two more tools
Color Checker
Add everyone in your party and see the whole bar at once. Pairs that are too similar to tell apart get flagged, so you know which one to recolor.
/waypoint Generator
Build a valid command to change a marker color — named color or custom hex — with the syntax checked against the version you actually run.
Locator Bar guides
The mechanic has moved twice since it shipped, so instructions written for one version fail on another. Each guide names the versions it applies to.

What players use it for
Server admins and players who needed a straight answer about the Locator Bar.
Two of my regulars had almost identical marker colors and kept walking to the wrong dot. The checker flagged the pair instantly and the generator gave me the /waypoint line to recolor one of them. Took about a minute.

I could not work out why the bar showed nothing after we updated. The not-working guide got me to the gamerule I had never enabled — it was the third item on the list, with the exact command.

I wanted my marker to match our team color before a build event. Pasting my username gave me the default hex, and the generator built the custom hex command without me guessing the syntax.

The UUID color breakdown is the only page I found that actually shows the hash maths instead of just handing you a hex. I could reimplement it in my own mod from that write-up.
