I created an algorithm that automatically creates outlines for the 4083 OpenMojis to make them work on dark backgrounds.

Look at all OpenMoji

OpenMoji is a free and open-source emoji-set by the University of Applied Sciences Schwäbisch Gmünd and collaborators.

Problem: There are 4083 OpenMojis and not all were well readable on dark backgrounds.

It be a daunting task to create a white outline manually, so I created an algorithm that does so in a few seconds.

A few examples how the outlining affects the readability

As of writing this the outlining algorithm isn’t included in the released OpenMojis yet, but one can follow the progress on Github.
