Bug with newsletter emails/dark mode

Bugs
1

Hi all,

This has been an ongoing problem, and I haven’t gotten any help from Ghost itself, so I thought I’d post it here. I have customized my newsletter template to have a Black background (specifically #121212), and every time said newsletter hits my inbox, the colors are alllll messed up. For context, I use Proton Mail in dark mode, and this is the only time this bug occurs. It also occurs regardless of the background color I try to use. I’ll attach a screenshot of it, and as you’ll see, the default purple background in Proton’s dark mode seems to override much of the color elements in the newsletter itself. I was wondering if anyone else has had this problem, and whetherh anyone knows of a way to fix this without just adjusting email appearance setting or getting a new email provider?

Thanks in advance.

I think this is a bug (or a side effect of a feature) of Proton Mail app itself: Dark Mode for Emails (not just the UI) – The Voice of the Proton Community

Is there anything you think I could do on my end in Ghost to override the issue? Whether it’s through coding, settings, etc. @muratcorlu

That I don’t know. I don’t use Proton Mai.

If you can see the issue by inspecting CSS code of email view in Proton Mail, maybe you can try to override that with custom CSS that you put inside an HTML card in post. This is the only potential solution came up in my mind.
