[1.15.2] Colouring a rendered GUI using code


Electrosphere

Recommended Posts

Hello! Like the title says im trying to change the color of my gui using code. My rendered gui is a custom health bar and im trying to change its color. I want to (in the future) make the color change based on my health but i cant manage to making it change from its default color of white.

 

Any help is appreciated! thanks
