Change specific line color according to error
已回答
Hello,
I am currently trying to figure out how I can change line number color according to an error. Much like the reference shown below:

To identify an error in the editor, I have used the PsiErrorElement class. However, I become confused on how to edit or apply color on the corresponding line number element. What is an appropriate approach to this?

There is no such possibility to change line number colors in editor gutter.
Thank you Yann Cebron for your response.
Do you think this implementation will be a priority in the future?
It seems not a popular request as I couldn't find related entry in issue tracker, if you want you can create one https://youtrack.jetbrains.com/issues/IDEA.
