# Appearance

> Colour, logo, corners, font, launcher position and icon.

## Your brand: General tab

Colour, logo, corners and font are set once under **Settings › Support settings › General › Branding** and used by both Messenger and the support form. The Messenger tab shows them with a **Change in General** link.

| Setting | What it does |
|---|---|
| **Brand colour** | Fills the header, the launcher and the buttons. Text and icons on it turn white or near-black automatically, whichever is easier to read. |
| **Logo** | Shown at the top of Messenger and on the hosted form page. PNG or JPG, up to 2 MB. Saved on upload. Without a logo, the first letter of your organization's name is shown. |
| **Corners** | **Square**, **Rounded** or **Pill** — how round the boxes, fields and buttons are. |
| **Font** | **Use my site's font** (the widget takes your page's font) or **Inter**. Inter is used when the visitor's device has it; the widget never downloads a font. |

## The launcher: Messenger tab

Under **Settings › Support settings › Messenger › Appearance**:

- **Launcher position** — **Bottom right** (default) or **Bottom left**.
- **Launcher** — **Show our button** (the round button in the corner) or **Only my own button**. With *Only my own button* there is no corner button; Messenger opens only from [your own buttons](/support/messenger/open-from-your-button/).
- **Launcher icon** — **Message bubble** (default), **Question mark**, **Headset**, **Chat dots** or **Envelope**, drawn in your brand colour.

When the launcher is shown, your own buttons work as well.

On phones (screens up to 480 pixels wide), Messenger opens full screen.

## Always shown

"Powered by CustomerCatalyst" is always shown at the bottom of Messenger and the form.
