    /bossbar add test "Test"
/bossbar set test value 100
/bossbar set test color red
/bossbar set test players @s

    → ✔ The text above the bossbar will appear red now

  2. Exit and reenter the world

Still affects 1.13-pre6!

It appears that the change of text color is unintended and happens as a temporary side effect of manipulating the boss bar using commands.

The culprit seems to be

net.minecraft.server.CustomServerBossInfo.getFormattedName()

where the boss bar's name isn't copied before it's manipulated and thus gets mutated (MCP names).

Still affects Release 1.15.1

It is also worth mentioning that running the following command after re-logging shows the correct color of the boss bar name:

/bossbar get <bossbar> value

A E
