MinecraftDecompiler VS threadtear

If you can read Java code, you can decompile and deobfuscate the client (for example with MinecraftDecompiler) and then search for "jeb_" in the code, which should eventually lead you to the code that decides the color cycle. I've never done this myself, so I can't give further assistance, but I'm pretty sure this approach would get you your answer if you can't find an easier way.

If you're very paranoid, Threadtear does have some amount of protection against potential code execution when decompiling, although it hasn't been updated in a while and it's still always a risk (albeit one I never personally encountered). If you suspect that the file you want to decompile does have a way to execute code when decompiling it, you could try using a virtual machine for some added protection.

I used recaf for the plugin.yml, I used deobfuscator to remove the obfuscation, then I used threadtear for decompilation. I use threadtear pretty much always, but it's allatori deobfuscation is somewhat lacking which is why I used a separate program. Also it does not show resources in the jar, which is why I had to use recaf.
