Facebook is introducing new branding for its products and services in an attempt to distinguish the company from its familiar app and website.
Instagram and WhatsApp are among the services that will carry the new FACEBOOK brand in the next few weeks.
The main Facebook app and website will retain its familiar blue branding.
The new logo, which is in capital letters, uses "custom typography" and "rounded corners" so the company's other products and app look different.
The branding also appears in different colours depending on which product it represents. So, for example, it will be green for WhatsApp.
"We wanted the brand to connect thoughtfully with the world and the people in it," Facebook said. "The dynamic colour system does this by taking on the colour of its environment."
Facebook's chief marketing officer Antonio Lucio said: "People should know which companies make the products they use. We started being clearer about the products and services that are part of Facebook years ago.
"This brand change is a way to better communicate our ownership structure to the people and businesses who use our services to connect, share, build community and grow their audiences.
"US Senator Elizabeth Warren has said she wants to break up the big tech companies such as Facebook, Amazon and Google and put them under tougher regulation.
This plan may be seen as Facebook's way of hitting back, although Ms Warren - posting on Facebook - said: "Facebook can rebrand all they want, but they can't hide the fact that they are too big and powerful. It's time to break up Big Tech."
