How to change usage highlight color in IntelliJ IDEA

Solution 1:

Go into Settings->IDE Settings->Editor->Color and Fonts->General

Make a copy of Darcula to something like MyOwnDarcula (can't change the built in schema).

Find whatever you need to change, in this case I think it's "Identifier under caret" and change the colors for foreground and background to your liking.

Solution 2:

The accepted answer is wrong. Editor>Colors & Fonts>General>Selection background/Selection foreground

Solution 3:

It's called "identifier under caret" and "identifier under caret (write)".

I suggest editing background color.

Solution 4:

Steps for your solution are:

1. File->setting or ctrl+alt+s
2. Got identifier under caret(For finding this click on code in general tab and enter identifier under caret). Refer image.
