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.

Try an example

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.

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.
