MULTIPLE COLOR SCHEMES
#058d77 is the theme color for Settings-related and Group-Info-related screens. These screens are information-orientated. Hence a neutral and relaxing theme color can build up an environment that facilitates users' understanding process.
#d7c2a5 is the theme color for Group-Chat-related screens. A heart-warming color always makes people more willing to communicate.
#A796F4 is the theme color for Media-Control-related screens. The magic violet always immerses people, which helps them focus on their tasks, such as requesting a song or turning on live streaming.

Next Song, Play/Pause, Rewind, Volume, Broadcast and Requested Song List are categorized into Media Control.
Song Request and My Album are categorized into Song Request.
QR code and Bullet Screen settings are categorized into Settings.
