Microsoft Outlook can do this, ProtonMail should be able to.

Temporary fix:

In browsers, it can be fixed by extensions like Styles. But why hasn't it been fixed yet? The desktop app doesn't have the temporary fix like the browsers.

Blinded by the white email background with everything else in dark mode is like staring up at the sun after walking out of a cave. No me gusta

Hmmm. I can't seem to enable dark mode for the Desktop app in Linux. I haven't found any menu option for it at all. It will only go into dark mode if I switch my entire KDE desktop mode - this is NOT what I want/need. I much prefer when apps themselves can be switched between light and dark modes.

I have to put my voice in here as well. Email content is dark on the apps but it's blinding on the desktop app which is where it needs to feel the comfiest.

I went to try the new desktop app, and this was the first issue I found. So frustrating to have dark mode on every part of the UI but the email body.

This is must have...

I agree this makes using Proton Mail really frustrating

Please add this. It is jarring to have an all-dark theme and then show a full-white body. Not standard UI

To be concise, do you mean that the background of the body field, of the email, and the text during composition should match the selected theme?

If so, I concur, because the theme "Monokai" is already synthwave awesome... It'd be even more awesome if the background was dark blue and the text was pink.

However, if you mean that all incoming emails should be changed to match our selected theme, I would have to disagree.

Although, if there was an option to view all incoming emails as plaintext, and that option served as a requirement to view all emails in the selected theme, that would be fantastic.
