# Users and colours

See who is in the session, who is online, and which objects each person holds.

The **Users** list shows everyone who has joined the session. Each person has a colour, which Rhino Sync also uses in the viewport, the chat, live previews and camera markers.

## Read the list

| Indicator                             | Meaning                                                                               |
| ------------------------------------- | ------------------------------------------------------------------------------------- |
| Person icon                           | **Current user**. That's you, shown in bold.                                          |
| Wi-Fi icon                            | **Online**. Rhino Sync heard from this person in the last 5 minutes.                  |
| Crossed-out Wi-Fi icon, grey name     | **Offline**. The person joined but isn't connected now.                               |
| Sync or download icon in their colour | The person is synchronizing or reloading right now.                                   |
| Red dot after the name                | **Broadcasting live previews**. See [Live Previews](/collaboration/live-previews.md). |
| Red warning icon                      | **User not on the same version**. Ask them to update.                                 |
| Version number                        | The Rhino Sync version the person runs.                                               |

## Show who holds what

Click the circle at the right of a row to **Toggle colour user objects**.

* **Filled circle:** colouring is on. Objects that person holds are drawn in their colour.
* **Ring:** colouring is off.

When you colour a teammate:

* Their objects are drawn in their colour, so you can see what's reserved.
* You can't select their objects, which avoids undone changes.

When you colour yourself, the objects you haven't synchronized yet are drawn in your colour.

Colouring only works while you collaborate. Rhino Sync refreshes the colours after each reload and synchronize.

## Show where a teammate is looking

Click the camera icon at the right of a row to **Show where this user is looking**.

* **Camera in their colour:** on. A marker in their colour shows where that person's view sits, with their name beside it.
* **Grey camera:** off.

The marker follows them as they navigate, and disappears about 10 seconds after they stop sending, such as when they end collaboration. Markers are drawn in model viewports only, on top of everything else, so a teammate behind a wall still shows.

Nothing is sent until you turn a teammate on, so a camera nobody watches costs nothing.

## Change your colour

Click the colour dot next to your name at the top of the **Sync** panel, or open [Settings](/reference/settings.md) and click the colour swatch. Pick a colour. Your teammates see it straight away.

Rhino Sync chooses a colour from your user name until you pick one.
