Hello I just noticed that tor browser is always using the system theme on any linux distribution. I use xfce so for example if my theme is set to Adwaita-dark or blue or whatever other theme , tor browser is picking that up automatically and the top bar and bookmark bar is following the system theme.
Is this a concern in terms of fingerprinting ?

Yes, Tor Browser should always be light theme, especially on Qubes-Whonix.
Tor browser is on light theme , on everything i visit like duckduckgo etc.
I am talking about the top bar were is the minimize / maximize buttons. that bar is following the system theme.
Also I am not asking this specifically for qubes…
Tor browser’s default theme uses os’s color scheme. Just like firefox. If os is set to dark grey colors lets say, tor uses the same palette. If os is set to shades of black, tor uses the same palette of shades of black. If os white, pale yellow, whatever, tor browser uses the same colors.

RFP always returns a light theme value for websites so the browser theme itself is not a problem.
For OS colors this is different, see the following github issue for more information:
