WhatsApp Brand Guidelines: The Green Bubble

Even the name is a joke you’ve probably said out loud a thousand times.

WhatsApp was founded in 2009 by Jan Koum and Brian Acton, two former Yahoo engineers, and the name is a straightforward pun on “what’s up.” The pitch was radical in its simplicity: reliable messaging that worked anywhere, on any phone, tied to your number rather than a new account. It grew so fast that in 2014 Facebook (now Meta) bought it for around $19 billion — one of the largest tech acquisitions ever. The brand’s whole personality flows from that origin: plain, human, unpretentious. A friendly green bubble, and a name that sounds like something you’d actually text.

The logo is almost the definition of a messaging app — a bubble, in green.

WhatsApp’s mark is a green rounded speech bubble with a white telephone handset inside — a two-symbol shorthand for “chat” and “call” that needs zero explanation in any language. It’s stayed remarkably stable, and it works precisely because it’s obvious: the speech-bubble shape is universal, and the bright green makes it pop on a crowded home screen. For a product used by billions across every literacy level and language, an instantly legible, self-explanatory icon isn’t a nice-to-have — it’s the entire design brief. (Our homage keeps the bubble but swaps the phone for generic typing dots.)

One bright, optimistic green — with a darker teal for depth. Click a swatch to copy the hex.

The signature is a fresh, upbeat green #25D366 — the colour of the bubble — supported by a deeper teal #075E54 and a mid #128C7E that you’ll recognise from the app’s interface. As always, treat these as widely-cited reconstructions rather than an official Meta spec. The green is doing quiet emotional work: it reads as go, positive, alive — friendlier than a corporate blue and calmer than a red alert. Copy the working values below.

WhatsApp barely brings its own type — and that restraint is on-brand.

The “WhatsApp” wordmark is custom lettering, but the app itself deliberately uses each phone’s system font — San Francisco on iPhone, Roboto on Android — rather than shipping a bespoke UI typeface. That’s a very intentional kind of humility: the app should feel like a native part of your device, not a branded overlay. The voice matches: WhatsApp describes itself as “simple, secure, reliable messaging,” leaning hard on end-to-end encryption and privacy. Plain type, plain words, a plain green bubble — the whole identity is engineered to disappear so the conversation can lead. The specimen below is set in a comparable neutral sans.

WhatsApp’s most recognisable piece of design isn’t the logo — it’s a pair of little checkmarks.

The app turned a handful of tiny status glyphs into a shared visual language understood by billions. One tick means sent, two ticks means delivered, and two blue ticks mean read — a system so intuitive it needs no manual and so socially charged that “the blue ticks” became a genuine cultural talking point about whether someone had seen your message and chosen not to reply. It’s a masterclass in microinteraction design: enormous meaning packed into a few pixels, working identically across every language and literacy level. Alongside the typing-dots animation and the plain contact list, it shows a brand whose real identity lives in behaviour, not decoration.

All of it flows from a founding constraint — WhatsApp had to work for everyone, everywhere, on any phone, including cheap handsets on slow networks in the countries where it became dominant. That forced a discipline of extreme simplicity: system fonts, a near-empty interface, a green that pops on any screen, and features added only when they truly earn their place. Co-founder Jan Koum famously kept a note taped to his desk reading “No Ads! No Games! No Gimmicks!” — a design brief as much as a business one. The restraint that makes WhatsApp look plain is the very thing that let it scale past two billion users. The identity endures because every part of it is engineered to get out of the way of the conversation.
