The look of your catalog pages is set in the **Appearance** section of the **Catalog** tab. In Neo Product Catalog Flipbook, go to **Flipbooks**, click the catalog’s title, then click **Appearance** on the **Catalog** tab. Make your changes and click **Save**.

This section designs the catalog pages. The viewer around them has its own **Theme** setting on the **Appearance** tab. See [Viewer colors](https://docs.neoflipbook.com/customize/viewer-colors/).

## Theme

A theme sets the fonts of your catalog. It also sets the colors, unless you pick a palette or custom colors.

| Theme               | Description                | Title font                             |
| ------------------- | -------------------------- | -------------------------------------- |
| **Paper**           | Crisp white & graphite     | Inter                                  |
| **Linen** (default) | Warm oat & rust            | Poppins                                |
| **Harbor**          | Cool mist & deep sea       | EB Garamond                            |
| **Studio**          | Chalk, ink & signal orange | Inter, with product titles in capitals |

Fonts come with the theme. To change them, pick another theme.

## Color palette

**Color palette** sets the page colors. The default, **Theme default**, uses your theme’s colors. Pick one of nine palettes to replace the theme’s colors while keeping its fonts.

| Palette        | Background | Text      | Accent    |
| -------------- | ---------- | --------- | --------- |
| **White**      | `#ffffff`  | `#1c1c1c` | `#5c5c5c` |
| **Slate**      | `#eff2f5`  | `#1d2733` | `#56697e` |
| **Wine**       | `#f7eef0`  | `#2b1519` | `#8e3b4f` |
| **Forest**     | `#eef3ee`  | `#18261c` | `#3f7a52` |
| **Ocean**      | `#ebf3f8`  | `#10222e` | `#2b7aa6` |
| **Terracotta** | `#faeee7`  | `#2d1810` | `#c0643e` |
| **Sand**       | `#f7f1e3`  | `#2a2416` | `#a88a4f` |
| **Blush**      | `#fbeff1`  | `#2c1a1e` | `#cf7f8d` |
| **Plum**       | `#f3eef7`  | `#211a2b` | `#7d5ba6` |

If you pick a different theme while a palette is on, the palette stays and only the fonts change.

## Custom colors

Turn on **Use custom colors** to set your own **Background**, **Text** and **Accent** colors. The fields start from the colors currently shown, so nothing changes until you edit one. Enter each color as a six-digit hex value, such as `#2b7aa6`.

The accent color is used for details such as the page header’s subheading, dividing lines and prices.

Turn **Use custom colors** off to go back to the theme’s own colors.

Only one color source applies at a time: the theme’s colors, a palette, or your custom colors.

## Page size

| Size             | Dimensions |
| ---------------- | ---------- |
| **A4** (default) | 210×297 mm |
| **Letter**       | 8.5×11 in  |
| **Square**       | 1:1        |

Every page in the catalog uses the size you choose, the cover included.
