[CRASH] Crash when parsing OptiFine properties for a trader llama (Invalid llama carpet colors)

[TheRainbowDerp06]

Loader and its version

Fabric loader 0.17.2

OptiGUI version

2.3.0-beta.8+1.21.9

Steps to reproduce

The game crashes when loading a resource pack that contains an OptiFine properties file for a trader llama with an invalid value. Instead of ignoring the invalid property and logging a warning, OptiGUI throws a fatal RuntimeException, causing the client to crash.

This occurs on game startup or whenever resource packs are reloaded.

I can't find colors=trader_llama in OptiFine documentation.
The error is logged here, and when I try to reproduce it, the game window doesn't close, I can play the game just fine. What you sent is a snippet of the log, not a crash report.
