Theme Color for TYPO3
=====================

[](#theme-color-for-typo3)

**EXT:theme\_color** (`t3/theme-color`) is a small TYPO3 extension for changing the backend theme color. You can set one global color for all users and optionally allow users to choose their own color.

 [![Theme Color extension icon](Resources/Public/Icons/Extension.svg)](Resources/Public/Icons/Extension.svg)

It is a lightweight solution for making the TYPO3 backend better match your brand or personal preference.

Features
--------

[](#features)

- set a global backend theme color in the extension configuration
- optionally allow backend users to define their own personal theme color
- user-specific colors override the global color when enabled
- supports TYPO3 backend themes `fresh`, `classic`, and `modern`
- includes a live preview in user settings for supported themes

Requirements
------------

[](#requirements)

- TYPO3 CMS 14.3 or higher
- PHP 8.2 or higher

Installation
------------

[](#installation)

### Option 1: Composer

[](#option-1-composer)

```
composer require t3/theme-color
```

### Option 2: TYPO3 Extension Repository (TER)

[](#option-2-typo3-extension-repository-ter)

Install the extension from the TYPO3 Extension Repository using the extension key `theme_color`.

Configuration
-------------

[](#configuration)

Open the extension configuration in TYPO3 and check these two settings:

### `theme_color`

[](#theme_color)

The global primary color for supported backend themes.

Only the `#rrggbb` format is accepted and stored canonically in lowercase.

Examples:

- `#ff8700`
- `#005fcc`

If this field is empty, no global color is enforced.

### `allow_user_update`

[](#allow_user_update)

Enable this if backend users should be allowed to override the global theme color with their own personal choice.

**If enabled:**

- a `Theme color` field is added to backend user settings
- that user-specific value wins over the global extension setting

**If disabled:**

- only the global color is used
- users can not set an individual theme color
