The GitHub logo for the code hosting and collaboration platform consists of a graphic mark and a wordmark. The mark is a circle with the cut-out silhouette of GitHub’s mascot, Octocat: a profile with a large oval head, small ears, and a curved tail; this pictogram is called Invertocat. Next to it, the name GitHub is written as one word without spaces, with capital “G” and “H”, set in a sans-serif typeface. The logo is used in black, white, and green; the Invertocat mark has only been refined in small details over time, while the GitHub wordmark has been updated several times. The name GitHub comes from Git (a version control system) and the word hub.
