SMS integration in Messenger will once again allow users to send and receive SMS messages from the app.
This color change feature is an optional feature that can be enabled or disabled in configs.
SMS support is not the only change coming to Messenger.
Facebook has also announced support for multiple accounts in the app for Android users.
The new multiple accounts feature is likely targeted at users who share their devices within the family or friends.
The new addition will mean that multiple people can enter to Messenger from a single equipment.
These can also be password-protected so only the account holder can read their messages.
Others will only see notifications that a message has been received and not its content.
Unlike the SMS option, this feature is available around the world.
