========================================
Feature: #108240 - Introduce Fresh theme
========================================

See :issue:`108240`

Description
===========

The new :guilabel:`Fresh` theme has been introduced for the TYPO3 backend,
marking the beginning of broader backend customization capabilities. This theme
offers users a modern alternative appearance option with a friendlier purple
accent color palette.

Built on the modern CSS architecture, the "Fresh" theme is now the default for
new users. It complements the existing Modern and Classic themes. All three
themes will be maintained and enhanced equally going forward.

The extensive CSS framework improvements made during the 14.0 cycle now enable
easier theme adaptation with minimal code changes, setting the foundation for
the expanding theme system.

Theme selection
===============

Users can select their preferred theme in the :guilabel:`User Settings` module
under the :guilabel:`Backend appearance` section. The "Fresh" theme provides a
more contemporary look and feel while maintaining the familiar TYPO3 backend
structure and usability.

All existing themes remain fully supported:

*   **Fresh** (default for new users) - Modern purple accent colors
*   **Modern** - Contemporary appearance with traditional accent colors
*   **Classic** - Traditional TYPO3 backend appearance

Future development
==================

Additional customization options and modern user interface elements will be
incrementally added to the theme system leading up to the long term support
release. The modular CSS architecture ensures that all themes benefit from
these enhancements equally.

..  important::

    The backend CSS framework is currently considered internal API. No public
    CSS variables or settings have been defined yet that are guaranteed to
    remain stable across future versions. Areas such as color palette
    generation, accent colors, stateful colors, and tinting mechanisms are
    still in active development and are subject to change before a long term
    solution is established.

Impact
======

The introduction of the "Fresh" theme demonstrates TYPO3's commitment to
providing a modern, customizable backend experience. The modular CSS
architecture allows for continuous improvement and evolution of the backend
design system.

New TYPO3 installations will automatically use the "Fresh" theme, while
existing users can opt in through their :guilabel:`User Settings`. The choice
of theme is stored per user, allowing teams with different preferences to work
comfortably within the same TYPO3 installation.
