How to change the color of errors in the code editor?

I am some what color blind. I am not fond of the new UI in IntelliJ due to this reason and avoided it.

But I am so often looking at something in IntelliJ on my co worker PC. Hence I am now trying to get use to it by actually using it.

I really have trouble seeing the difference beteween `public void` and the `Some_invalid_code` in the editor itself. If I really focus I do see it but I do not enjoy working this way.

I know I can adjust the color of the terminal window (File | Settings | Editor | Color Scheme | Console Colors) to be a brighter red.

Which I can see easily.

How can I do the same for errors inside the code editor?
