If you want to adjust the style of your player, such as the player colours or the playlist settings, you can use the Design tab found in Player Settings.
When you click on the Player Settings option, you do not see a line of tabs, one of which should be Design or Social.
The reason for this is due to your user permissions. For these tabs to show, you need to have the Edit Player Style & Restrictions set to ON.
Please contact your Vidyard Admin (internal to your organization) to either allow this permission for your particular role, or they could move you into a different role that has this option enabled.
Role permissions are found in Group > Groups & Users, then the Options button on a role.
