To edit your workspace's logo, name, font and color scheme as well as your default schedule name, head to the settings menu in the sidebar and select general. Note that you must be an Admin to access these settings. 

You can choose your font and primary and secondary colors, which can match your workspace branding and will be used for things like Event Briefs and Schedules.

This is also where you can change your workspace name and the default name given to Schedules across your Workspace.
