If you want the more future proof in-code solution that doesn't require an arbitrary hardcoded string interpolation,
this call on the `TextComponent` will color it. You can use any ChatFormatting enum constant, including ones that are added after the fact, and you don't have to consult some table on the internet to find what you want.
TLDR: The vanilla launcher is crap, so we have to do a work around which is screwing up on creeperhost.
To my knowledge, if Structurize isn't in the list of mods, it'll work on 1.16.5 by default, without you needing to change anything.
We implemented a Version Compatibility Matrix to make this easier for you.
