Theme colors documentation


Short Overview

To help during the betas here’s a quick mapping of some colors in the JSON files.

Many of the colors respect M3 1.2 colors roles (Material Design 3 for Compose 1.2 - Material Design and Components – Material Design 3)

But some colors have been assigned specific roles to allow more variations in the themes:

  • surface: The default background
  • surfaceContainer: The navigations bars and compact player default color
  • surfaceContainerHigh: Dialogs background. Bottom sheet headers. With alpha as overlay background. Cards
  • surfaceContainerHighest: Snackbars.
  • surfaceContainerLow: Shorcuts. Some buttons. Missing image background. Filtered library. Missing image background.
  • surfaceContainerLowest: Bottomsheet background
  • outlineVariant: Default M3 roles. With alpha currently active row.
  • onSurfaceVariant: Default M3 roles. With alpha subtitle texts.

Theme Framework

The Symfonium UI consists of several components (e.g. a search bar), which again break down into singular elements (e.g. the search bar background, the search text, …). Each element has a color role assigned. In the custom theme JSON file, you can define the exact color applied to each color role. Through that, elements get their colors and components get their overall theme.

The Symfonium UI consists of Components which consist of one or more Elements which each are assigned a Color Role which has a specific Color Value.


In the following screenshots you see components (in red) and elements (in green) labeled. The elements belonging to one component are usually not shown, but you can find them listed in the components table.

Some of the screens are configurable and might look different depending on your settings. This is especially the case for the home screen.

Home Screen and Main Navigation

The Home Screen is very configurable, but in the end consists of several sections with an optional heading and some kind of media listing. The layout of the listings can be configured. The same goes for the shortcut buttons. We see the same elements, no matter which layout is chosen.

The main navigation is visible at all times (except when entering the settings, or when disabled) and presents itself as a container which lays over the main app content.

Home Screen Media and Shortcut Button Display Styles

To illustrate the similarity of the elements in different home screen section layouts, you can see them here side by side.

Album View and Mini Player

Besides the cover image, the album view features buttons and the tracklist.

The Mini Player works similar to the main navigation as it lays on top of the main application content.

List View and Selections

Artist, albums, genres etc. can be displayed in lists. The list layout is configurable similar to the home screen sections, but the same elements are used in different layouts. When selecting items in a list, an action menu pops up over the list contents.

Bottom Sheets

Bottoms sheets contain contextual information or menus. They temporarily slide over the the application (including the main navigation).

Search Screen

The search screen is devided into the search part on the top and the result list on the bottom.


The settings pages consist mostly of strctured text lists with switches or selectable items. Sometimes the items can be moved (ordered).
