healthbar help

[balmy wren]

I want to make my health bar work kind of like deepwoken with it flashing red and a different color when you take damage but i dont know how to. I went through the struggles and managed to make a custom ho bar yesterday but cant figure this out.

Help would be appreciated 🙏 😭
