Bug description

PolyColor constants are shared mutable singletons, meaning if you use the same constant (e.g. PolyColor.WHITE) as the default value for multiple config options, changing one of them changes all of them (changes take effect after closing the OneConfig GUI).

Steps to reproduce

1. Launch a client with REDACTION 2.0.0 (not 2.0.1+)
2. Open the config
3. Change Snow Color or Line Color
4. Close the config
5. Reopen the config
6. Observe how both have changed to the same color

Anything else?
