Many people have a problem with the fact that WhatsApp uses a yellow double circle as a message indicator, and that there is no other indicator for the green check. In addition, not all colors are equal. For instance, in the case of the blue and black messages, there is a good chance that the double circle will remain unknown, even if you have the application installed and use it.

This is a simple and useful solution for those who are suffering from problems with color vision. All you need to do is install this extension for WhatsApp Web. It will be updated to work with the latest versions of the application, so you don't have to install anything else.
