Problem

If file is modified, I want to change the color of the file name.

Expected behavior

Ex. barbecue.nvim

From your screenshot it seems like the whole icon instead of the background is changed. Would you like to change the background only or change the whole icon?

EDIT: never mind, I see you changed the title.

It is good if I can change both text color and icon, but easier is fine because I'd like to know that the opened buffer is modified.

Thanks!
