About Locator Bar

Locator Bar is a small, free set of tools for one narrow Minecraft mechanic: the Locator Bar that Java Edition added in 1.21.6, and the waypoint colors that go with it. Three tools — a color finder, a color checker, and a /waypoint command generator — plus a set of guides covering the rest of the mechanic.

Why this site exists

The Locator Bar assigns every player a color automatically, and that color is not shown anywhere in the game. If two people on a server end up with markers that look alike, there is no in-game screen that tells you so, and no in-game way to preview what a color change would look like before you type the command.

That is a small problem, but it is a real one, and the answers were scattered: some on the wiki, some in snapshot changelogs, some only in decompiled source. This site puts them in one place and makes the color part computable.

How the color figures are produced

Every color on this site is computed in your browser from the player's UUID. Nothing is looked up from a database of pre-computed answers, and no color is guessed.

The derivation uses Java's UUID hash, takes its low three RGB bytes, and sets HSV brightness to 0.9 while keeping hue and saturation. It does not multiply RGB channels by 0.9.

On 14 September 2026 we corrected the earlier algorithm and checked the official 1.21.6 and 26.2 client code. Notch's default is #E66185. This is a version-scoped code result, not a guarantee about future clients, mods or team overrides. The UUID color guide records the correction and derivation.

What we source, and what we flag

The guides cite primary sources — the Minecraft Wiki, Mojang's own snapshot and release changelogs — and link them at the foot of each page. Where something is genuinely undocumented, the page says so instead of filling the gap with a confident guess. Three examples of things currently marked as unverified:

• Whether a player in another dimension appears on your Locator Bar. Community consensus says no; we found no official statement either way.
• Whether future versions retain the verified 1.21.6/26.2 color arithmetic.
• Whether renaming a Minecraft account can ever change its UUID. The practical answer is no, but we could not find one official page stating it outright.

Version details matter here more than usual, because this mechanic has moved: the game rule was useLocatorBar, then locatorBar, and is locator_bar from Java 1.21.11 onward. Guidance written for one version fails on another, so the guides name the version each instruction applies to.

Username lookups

The finder, checker and generator accept a Java Edition username as well as a UUID. Our server resolves usernames through Mojang's public profile API, with PlayerDB as a fallback when needed. We do not write usernames or results to an application database. A username can appear in our hosting provider's normal request logs because it forms part of the lookup URL. See our Privacy Policy for these providers and data handling.

Who runs it

Locator Bar is run by IndieLucas, an independent developer. The site is not affiliated with, endorsed by, or connected to Mojang Studios or Microsoft. "Minecraft" is a trademark of Mojang Studios; this site is an unofficial fan resource.

Corrections

If something here is wrong — and on a mechanic this new, some of it will be — tell us and it gets fixed. Version-specific corrections are especially welcome, as is anything where we have marked a fact unverified and you have a primary source that settles it.
