You are allowed to use the built-in vanilla resource pack as well as the built-in programmer art resource pack in versions that have it built into the game. In addition, you are allowed to use resource packs for accessibility reasons - colorblindness, sensory issues, etc... If you want to be safe, just use the vanilla resource pack

whitelisted resource pack modifications are listed here https://bit.ly/extrarules
