A simpler set of options than some apps offer
Unlike apps with an extensive store of purchasable app-wide themes, WhatsApp keeps this to a straightforward choice between light, dark, and following your system setting β there's no separate marketplace of colorful themes to browse.
Different from a chat wallpaper
This setting changes the app's overall colors everywhere. Setting a custom background image behind the message bubbles in one specific chat is a separate feature, covered in its own guide.
Frequently Asked Questions
Is this the same as a general phone dark mode setting?
It's related but distinct β this controls WhatsApp's own appearance specifically. Choosing "System default" makes it follow your phone's overall dark mode setting automatically, but you can also override it independently within the app.
Does switching themes affect my chat history or settings?
No β this only changes the app's visual color scheme. It has no effect on your messages, contacts, or any other settings.
