@codebytere curious, is this behind an option that can be selectively enabled or disabled? I can imagine that an app might want to decide to have it and/or even control the accent color if possible?

@bpasero sure, i think that's possible here! I can rework this to allow for a bit more control.

@bpasero tweaked it a bit to allow disabling border or setting to a custom color.

@codebytere great, eager to give it a try

Release Notes Persisted

Added support for customizing system accent color and highlighting of active window border.

I have automatically backported this PR to "37-x-y", please check out #47537

@codebytere this works really well:

Quick question: is there any way we could force this color, even if the user has disabled accent colors in Window settings?

@codebytere also curious if this color could be set after the window has opened, so that we could set the color differently per workspace that is opened (a popular request actually: https://marketplace.visualstudio.com/items?itemName=johnpapa.vscode-peacock)

@codebytere also, this does not seem to override the accent color when frameless window is not used (i.e. native window frame is used) so I would make that clear in the settings description.

@bpasero hmm, do you have a sample? Running the following:

const { app, BrowserWindow } = require('electron')
const path = require('node:path')

function createWindow () {
  const mainWindow = new BrowserWindow({
    accentColor: 'green',
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  })

  mainWindow.loadFile('index.html')
}

app.whenReady().then(() => {
  createWindow()

  app.on('activate', function () {
    if (BrowserWindow.getAllWindows().length === 0) createWindow()
  })
})

app.on('window-all-closed', function () {
  if (process.platform !== 'darwin') app.quit()
})

Produced:

As expected for a framed window.

I'll look into #47285 (comment). As for forcing it when it's user-disabled - probably, i'll take a look at that too.

@codebytere yes disregard, that seems to work. What does not seem to work is to disable the accent color when it is set in Windows, but that seems fine to me.

So to summarise:

• a way to force the color even if the windows setting is off
• a way to update this after a window has been opened

@bpasero could you please open a follow-up issue for updating the color after the window is created?
