If you set up a color as primary, then that color is not guranteed to be used as it is. Due to accessibility restrictions that color might be slightly adjusted to fulfill the color contrasts requirements.

Meaning when setting the default color of #0082C9 then you will get #0091f2 on the bright color theme for elements (e.g. those primary buttons).

The reason for this is the mime type icons returned by OC.MimeType. Primary colors are not adjusted to the correct used colors.

That's a fix for the recommendation app, no?

I think this will resolve the issue of inconsistently: nextcloud/server#45163

Still an issue on NC 29.0.1

I think the issue is IconBuilder::colorSvg that calls elementColor without background color so the color might be different to the color used for buttons.
Problem here is that we do not know if it has dark theme or bright theme.
