# Dark Mode tab

Joomla's backend has its own light and dark mode. Admin Customizer respects that: **by default it does nothing special to dark mode**. It leaves Joomla's dark theme in place and derives your brand colors for it automatically, so you get a consistent dark mode for free.

 You only need this tab if you want to override specific dark colors, for example to match an exact brand shade.

## Custom Dark Mode Colors

 **Custom Dark Mode Colors** – The master switch for this tab.

 
- **No** (default) – all dark mode colors are derived automatically from your light mode settings.
- **Yes** – reveals the color fields below so you can set specific dark colors. Any field you leave empty keeps its automatic color, so you can override just one or two values.

 ``

 When the switch is on, you can override the following. Every field overrides the automatically derived dark color; leave it empty to keep the automatic value.

 **General**

 
- **Brand Color** – the brand color used in dark mode.
- **Text on Brand Color** – text and icons on top of the dark brand color.
- **Link Color** – link color in dark mode.

 **Backend**

 
- **Body Background Color** – the backend background in dark mode.
- **Header Background Color** – the backend header in dark mode.
- **Sidebar Background Color** – the backend sidebar in dark mode.

 **Login Page**

 
- **Body Background Color** – the login page background in dark mode.
- **Header Background Color** – the login header in dark mode.
- **Login Box Background Color** – the login box in dark mode.
- **Sidebar Background Color** – the login sidebar in dark mode.

 **Tip:** Start with the switch off and check how the automatic dark mode looks first. In most cases it's already right, and you'll only need to nudge one color.
