   e SoundCloud (laranja) se misturam. Fundo tinta fria e quase-preta
   (não o aubergine morno de antes), texto branco-frio nítido (a cor
   antiga do texto "puxava" pro creme e ficava murcha sobre o roxo/
   âmbar), e um terceiro tom — o "acento M+" — que é DO APP, não de
   nenhuma plataforma, e é customizável nas Configurações > Aparência.
