I want my gameobject Fade from red to white,and repeatedly.

I believe this is what you're looking to do. It is pretty straight forward you're just blending between two colors and controlling the opacity with the sine of time.

An additional note you can alter the behavior of the blink by replacing the sine node with any of the wave nodes (E.g square wave for a strobe effect).
