We as a developer sometimes need a change to make our tools look different.
You can add a small(I prefer 96px x 96px) logo.png
image file to the root of your repository.
Which makes your project more specific and easy to find with gitlab or SourceTree git client. Unfortunately github does not support this feature.
It is very simple but it works!
Update: Thanks to your comments I have found another way within Gitlab repository settings:
hope you enjoy this trick and make your tools more fun :)
