Q:

Change contrast in PhpStorm

I don't know, it may be off topic question. I am using Darcula theme in PhpStorm. I need to add more contrast (darker background, brighter text) in PhpStorm.
I googled a lot but I could not find appropriate answer for changing that. Is there any way to do that?

A:

While this post is dated, searching for an answer to what I believe to be a similar problem brought me here. In my case I could not easily read the line numbers on my display. The contrast was too weak.
I will answer this with the steps I took as it may help others who stumble onto this: 
To configure it I opened Settings/Preferences dialog, and under the Editor node, clicked Colors & Fonts and then the General section. In this section I was able to find Code => Line number (in my case). In the case of the OP the section will be Text => Default text.
There you can change the colors and contrast directly to your liking.
