How to make the entire scene in Unity greyscale but only shows the red color?

in Unity
Hey guys,
I'm a game artist generalist and I barely use Unity, so I was wondering if I want to make my entire scene grey scale except the red color, I want the red color to show (eye glowing for zombies)
So literally no idea how to do this, any help on the subject?

Color grading can do this. Look up post processing. Easiest way might be using a Look Up Table (LUT). You basically feed it a palette that replaces the final screen colors with your new ones. So you would use a greyscale palette, except from the reds.
If there are other red bits in your scene that you don't want to stay red, then it might be good to add a special effect texture to the zombie eyes, which you can use to isolate those areas in the post process. -
Another way to do this is with replacement shaders. Add a grey scale replacement shader to the main camera. Render the eyes with another camera and set it's clear flags and depth appropriately.
