How do you make image links in the Main Menu light up/glow when hovering?

Hey, I’m trying to make the image links in my game light up or glow when hovering “Like some website links do” I’m new to Unity and don’t really know a whole lot C# yet. If someone could help me figure out what to do that would be great. Thanks.

Hope these will help you. You can use renderer.material.shader to set shader self-illumin, light.enabled = true to make an object glow. I hope you will figure out other things :).
