WhatsApp has introduced dark mode, designed to reduce eye strain in low light environments and to prevent the user’s phone lighting up brightly in a dark room. In launching dark mode, WhatsApp described it as: “the most requested feature from our users everywhere”, and said it will roll out in the coming days on the latest version of WhatsApp.
When designing dark mode, WhatsApp said it spent time researching and experimenting with a focus on readability and information hierarchy. On readability, when choosing colours, it aimed to minimise eye fatigue and use colours that are closer to the system defaults on iPhone and Android respectively.
On information hierarchy, the aim was to help users easily focus their attention on each screen, by using colour and other design elements to make sure the most important information stands out.
Users on Android 10 and iOS 13 can use dark mode by enabling it in system settings. Users on Android 9 and below can go into WhatsApp Settings > Chats > Theme > select ‘Dark’.
