Per-editor/tab background color

[fabiospampinato]

It would be awesome to have the ability to change the background color of an editor/tab on a per-editor/tab basis, programmatically. The use case I'm thinking about is ToDo files, but there might be others.

For instance this is what a todo file might look like in VSC:

This is what it looks like in Sublime:

Having those editors/tabs in a different color makes them stand out.

Also, some decorators used by the VSC extension in the screenshot are necessarily dynamic, and because of #32813 the colors used in them are provided via the settings. This means that if a user changes its theme he/she will also need to change those settings for those decorators to not look out of place. With the ability to set a custom background colors those decorators will look right no matter the theme.

I really really need this feature.

I agree. The current UI looks like the tab that I'm on is not selected (and vice versa). The selected tab colour should be lighter (grey) and other tabs should be darker (black).

I think it would be useful in a multi-root environment, for tabs to inherit the colours of their relevant project settings. It gets confusing juggling grey tabs in a client/server environment.

Would definitely love colored tabs

There is an extension that does exactly this -
ColorTabs
You can choose what you want to color, the tab, the title bar etc. based on a regex

@oreporan I don't think that extension can achieve something similar to what Sublime provides. Besides I'm asking for an API for this, which I would in turn use in my extensions.

Oh my bad - overlooked the "programatically" part in your original post

Anyways, some of the other comments seem to be looking for something that this extension provides if I understood correctly

I would love to have this feature too!
Currently I have a medium sized backend and many frontend applications within the same workspace (repository).
It starts to get confusing whenever I touch files across all sub-projects. Colored tabs would greatly help here - they build up a mental model and help to orientate a lot.

It would be incredible if when working in a multi-root project you could define custom themes for each root folder. Ideally, these settings could live within a .vscode folder of each root folder as well as within the *.code-workspace file!
