Viewer colors set the look of the viewer around your pages, such as the background behind the book and the toolbar. They don’t change the pages themselves. Where you set them depends on the flipbook type.

## PDF and image flipbooks

1. In Neo Product Catalog Flipbook, go to **Flipbooks** and click the flipbook’s title.
2. On the **Flipbook** tab, click **Appearance** to open the section. It’s closed by default.
3. Pick a theme or a palette, or set your own colors.
4. Click **Save**.

> **Two things called Appearance**
>
> The viewer colors are in the **Appearance** section of the **Flipbook** tab. The separate **Appearance** tab holds the toolbar settings. See [Toolbar and navigation buttons](https://docs.neoflipbook.com/customize/toolbar/).

The section gives you three ways to color the viewer:

| Option            | Choices                                                                                                                                                                                                               |
| ----------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Theme**         | **Light** (default), **Dark** or **Sepia**. Each card shows a small “Title / Body & link” sample in its colors.                                                                                                       |
| **Color palette** | **White**, **Slate**, **Wine**, **Forest**, **Ocean**, **Terracotta**, **Sand**, **Blush** or **Plum**. Each card shows the palette’s three colors. These are the same palettes product catalogs use for their pages. |
| **Custom colors** | Your own **Background**, **Text** and **Accent** colors, as six-digit hex values such as `#1f6f8b`.                                                                                                                   |

Only one of these applies at a time. Picking a theme or a palette replaces what you had before. Editing a custom color takes over from both, as the note in the section says: “Editing a color takes over from the theme or palette above.”

The **Custom colors** fields always show the colors in use. To start from something close to what you want, pick a palette first, then change just one color. If you type a value that isn’t a full hex color, the app keeps the last valid color.

## Product catalogs

A product catalog has no **Flipbook** tab. Its viewer colors are set with the **Theme** select on the **Appearance** tab: **Light** (default), **Dark** or **Sepia**.

This only colors the viewer around the pages. The design of the catalog pages themselves, such as their fonts, colors and palette, is on the **Catalog** tab. See [Themes, colors and page size](https://docs.neoflipbook.com/product-catalogs/themes-and-colors/).
