使用IntelliJ IDEA进行调试时，不同的变量颜色是什么意思？

Question

So when debugging with IntelliJ IDEA, the Variable Window often looks like this:

(the white box is added by me afterwards)

Now i have some variables colored red, others colored blue.

Whats the meaning of the color, what is difference between these colors? I have also noticed red variables with blue fields and the other way around.

I didnt find anything on the web about this.

Answer 1

Red is the standard color for variables.

Blue indicates that a variable has changed while you're stepping through the code. If you continue to the next iteration of your loop (assuming offlineNotifications is a Collection), you will see those are the variables manipulated in the current execution of code.

Answer 2

For me, non-project files are set to brown, and tests are set to green. I think you may also define colors for other file types
