We have a slight problem with colors in Nextcloud 25, which I noticed this week. It looks like the server color capability now depends on each user's background picture. But this is a problem because:

• The app will look inconsistent (actual server color during and immediately after login, then user color next times)
• The background image is never actually shown in the app
• This will be a problem for branded clients, where we want brand color to be consistent all the time.

For these reasons I believe we should have a way to retrieve the true "server color" independently of user background, and always use that for the mobile apps.

Thoughts @AndyScherzinger @jancborchardt @tobiasKaminsky ?

Tricky topic because there is also the opinion that the wallpaper related primary color is the one to be used on the mobile apps also despite them not using the wallpaper.

As for the enforcement, you can do that on the server by disabling this completely for server and clients all together. So I can't tell if you just want to be able to keep the flexibility available on server but restrict it on clients.

So interested in the other mentioned peoples' opinion as well as @karlitschek

The app will look inconsistent (actual server color during and immediately after login, then user color next times)

How about we do this:

• Use our blue color for during log in process
• As soon as the account is connected we fetch the person’s color, or fall back to server color

That way we don’t have a worst-case 3-step color switch. And we really need to make sure this inconsistency does not exist, which we can by optimizing the loading, no?

The background image is never actually shown in the app

So the splash screen is the 1 thing which we can unfortunately not edit (only in branded clients). But we might still want to use the background e.g. in the header part of the navigation.

This will be a problem for branded clients, where we want brand color to be consistent all the time.

This actually depends on the customer I’d say. Admins could disable the functionality for people to set their own background. (Not sure if this is already implemented.)
