Make material flicker when hit

Hello,

I would like to make object’s material flicker when it’s collider collides with something.
Like in some arcade shooter’s games if you know what I mean

I need a tip!

Use Renderer.Material.color:

You can also use change the enabled state of the Renderer (because in some old games the characters disappear and reappear when hit)

I will test your suggestions, thanks guys
