I really like that VSCode colors the file name in the sidebar depending on the git status (green for new, yellowish for modified). What I don't like is the file names for the tabs don't also reflect that. Is there a way to make the tabs use the same colors as the sidebar? Additionally, are the colors configurable for the different git states?
Dec 2020: This is not likely, because there are a lot of issues/plugins already around tabs colors for VSCode (like issues/31308)
That means any text color you might want would likely clash (be less readable) with the foreground/background tab colors imposed by a setting or a plugin (like ColorTabs).
That is why custom text colors are better represented in the sidebar rather than the tabs themselves.
Update VSCode 1.53 Jan. 2021: as described with Mark's answer, this is implemented in term of tab decoration:
Tab decorations
Two new settings allow you to configure whether editor tabs show decorations, such as
git statusor diagnostics.
- Use
workbench.editor.decorations.colorsto decorate tabs with colors, like red/green for files with errors and warnings, and- use
workbench.editor.decorations.badgesto decorate tabs with badges, like M for git modified.
