Avatars are used to quickly identify users or teams.
Teams
When displaying a team’s identity, we badge the avatar with a shield. We fall back to the first letter of their name and a color we choose at random. As team administrators add more data—choosing a color or uploading an avatar—we progressively enhance the avatar.
In this example, from left to right, we have a team name of Hum with no avatar or custom color. In the middle we have a team name of Hum with a custom color. In the last example, we have a team name of Hum with a custom avatar applied.
