In my Chrome extension, I'm adding a panel to the Developer tools window. By default, the background of my html panel page is white, but I want it to show the correct background color when user switches to dark theme.
I can query the current theme via the chrome.devtools.panels.themeName property, but from there I don't know what the right color code to use for the background if the current theme is the dark theme. The background of the developer tools window is some shade of black. I know it's not 'black'.
