GitRainbow is a Chrome add-on developed by jasonkarns that adds a splash of color to your GitHub commit history. This free tool uses each commit's sha-hash, specifically the first 6 characters, as a hex color to create a visually appealing representation of your commit history.

With GitRainbow, you can easily distinguish and identify different commits at a glance. Each commit is assigned a unique color based on its sha-hash, allowing you to see patterns and trends in your GitHub history. Whether you're working on a personal project or collaborating with a team, GitRainbow adds a touch of vibrancy and organization to your commit history.

This Chrome add-on is a great addition for developers who want to make their GitHub commit history more visually engaging. GitRainbow is easy to install and use, making it a convenient tool for enhancing your GitHub experience.
