Nextcloud theme is dark by defualt while the user theme is Light

[elhananjair]

Describe the bug I have a light theme applied on nextcloud, and I selected Nextcloud theme snappymail setting. By default, it is dark, but currently I am using Light theme therefore it doesn't look nice.

To Reproduce Steps to reproduce the behavior:

1. Go to setting
2. Click on themes
3. Select Nextcloud from the theme list
4. The dark background color appears

Expected behavior Should be the same with Nextcloud applied theme

Screenshots Please complete the following information:

• Browser: Firefox 106
• IMAP daemon: [e.g. courier, dovecot]
• PHP version: 8.0.25
• SnappyMail Version: 2.20

SnappyMail 2.20 uses var() settings in CSS of your theme. So your theme might have issues.

Try Nextcloud default or Breeze Dark.

Also report which Nextcloud theme you are using.

@the-djmaze as you might see in the pic am using Nextcloud theme on snappy mail and the Light theme on Nextcloud.

Right. Where do you set the default to Dark? Because i can't find that option in my Nextcloud

[the-djmaze]

Did you try the embed mode?

Ah, you are using Nextcloud 25. Because everything works fine in Nextcloud 24.

So i went and installed Nextcloud 25 and i noticed that the theme of NC25 is horrible.

You should report to Nextcloud that there is something wrong with the :root variables.

Because SnappyMail just maps its own variables to that of Nextcloud. Like:

:root {
    --main-bg-color: var(--color-main-background)
}

But --color-main-background is black, not white in NC25

The issue is the way how NC25 controls theme colors

[data-theme-light] {
    --color-main-background: #fff;
}

Fixed in v2.20.1
