modify colors of SettingsWithSidebar

[Joerg B]

Hi, 
I am wondering how to modify the colors of the font used in the sidebar.
In my .kv I am modifying the Button like this:

<Button>
    background_normal:app.get_asset_path(app.theme.button_normal)
    background_color:app.color('button')
    color:app.color("font")
    on_press: app.background_color(self, 1)
    on_release: app.background_color(self, 0)

The problem now is, that when using a light theme with a black font on the button, the sidebar of the settings screen is all black.

So far I could only figure that I can change the content on the right with:
<SettingString>: 

      Label:

How do I control the buttons used for the sidebar? 
Is there any documentation about that? I wasn't able to find much so far.

Thanks a lot in advance
Joerg

I just figured It's not the button thing I'm doing, it's modifying Label. 
I can easily work around that.

I could sort it out by myself.
In case anyone else will have this question:
Everything to adapt the colors of the settings page is in:

.../site_packages/kivy/data/style.kv

from kivy.uix.settings import SettingsWithSidebar

class MyApp(App):
    def build(self):
        self.settings_screen = SettingsWithSidebar()
        return self.settings_screen

    def on_theme_change(self, new_theme):
        # Adjust sidebar color when theme changes
        sidebar = self.settings_screen.children[0]  # Assuming it's the first child
        sidebar.background_color = self.color('background')  # Use app theme color

thanks for showing me that way. 
I was actually thinking too complicated. In the end I simply changed the background color of the whole settings screen. All widgets in use there are already modified anyways. 
I added this to my .kv:

<Settings>:
    orientation: 'horizontal'
    canvas.before:
        Color:
            rgb: app.color("background")
        Rectangle:
            pos: self.pos
            size: self.size

Now it's got the look and feel of the rest of the app.

I would recommend you add a "-" to the kivy rule.  This redefines the widgets style.  

<-Settings>:

    orientation: 'horizontal'
    canvas.before:
        Color:
            rgb: app.color("background")
        Rectangle:
            pos: self.pos
            size: self.size
