## Description

**Aticolor Palettes** lets you build and maintain a personal color library right
inside WordPress. Ideal for designers and developers who work on multiple sites 
and want quick access to project color palettes.

**Key features:**

 * Color groups — organize colors by project, brand or category
 * Toolbar access — click the palette icon in the admin bar for instant access from
   any page
 * Full admin page — manage your palette from a dedicated, spacious interface
 * One-click copy — click “Copy” on any color to send the hex value to your clipboard
 * Transparency support — opacity slider + 8-digit hex (#RRGGBBAA) for colors with
   alpha channel
 * Add, edit and delete — full CRUD for both groups and colors
 * Remembers collapsed groups — the dropdown remembers which groups you collapsed
 * Persistent storage — your palette is saved in the WordPress database
 * Internationalized — available in English and Spanish (and ready for more languages)

### External Services

This plugin optionally connects to Ko-fi (https://ko-fi.com) when you click the “
Support this plugin” button. The Ko-fi donation page is loaded in a modal iframe
solely to allow voluntary donations to the plugin author. No data from your WordPress
site is sent to Ko-fi automatically — the connection is only made when a logged-
in admin explicitly clicks the button.

## Installation

 1. Upload the `aticolor-palettes` folder to the `/wp-content/plugins/` directory
 2. Activate the plugin through the **Plugins** menu in WordPress
 3. Click the palette icon in the admin bar to start adding colors

## FAQ

### Will this plugin affect my site’s frontend?

No. All CSS and JavaScript is only loaded when the admin bar is visible (i.e. when
a logged-in user is browsing), and the plugin does not modify any site content.

### Where is my palette data stored?

In the `wp_options` table, under the key `cpm_palette_data`. If you uninstall the
plugin this data is automatically removed.

### Can I use transparent colors?

Yes. The color form includes an opacity slider and accepts 8-digit hex codes (#RRGGBBAA).
Opaque colors are stored as standard 6-digit hex (#RRGGBB).

### Can multiple users have separate palettes?

Currently the palette is shared across all admin users of the site. Per-user palettes
are planned for a future release.
