Laratone is a comprehensive Laravel package for managing color libraries and swatches in your applications. It provides an easy-to-use API for storing, retrieving, and managing color data, with built-in support for various color formats (HEX, RGB, CMYK, LAB, OKLCH) and popular color libraries.
- Multiple built-in color libraries (Solid Coated, GuangShun Thread, HC Twill)
- Auto-calculation of RGB, CMYK, LAB, and OKLCH from hex values
- Find closest matching colors using LAB or OKLCH distance algorithms
- Configurable white point reference for LAB color calculations
- Automatic color data caching with configurable TTL
- Easy color book management and seeding
- Flexible REST API with filtering, sorting, and pagination
- Type-safe color value casting (LAB, RGB, CMYK, OKLCH)
- Full PHP 8.4 support with strict typing throughout
- PHP 8.4 or higher
- Laravel 12.x or greater
Note: For PHP 8.3 / Laravel 11 support, use version 4.x of this package.
You can install the package via composer:
composer require daikazu/laratonePublish the configuration file:
php artisan vendor:publish --tag="laratone-config"Publish and run the migrations:
php artisan vendor:publish --tag="laratone-migrations"
php artisan migrateThe published config file (config/laratone.php) contains the following options:
return [
// Table prefix for Laratone tables
'table_prefix' => 'laratone_',
// Cache duration in seconds for color books and colors
'cache_time' => 3600,
// Reference white point for LAB color calculations
// Options: 'D50' (print), 'D55', 'D65' (daylight, default), 'D75'
'white_point' => 'D65',
// Default algorithm for finding closest colors: 'lab' or 'oklch'
'default_match_algorithm' => 'lab',
// Maximum number of colors that can be returned by find-closest
'max_match_limit' => 100,
];When RGB, CMYK, LAB, or OKLCH values are not provided, they are automatically calculated from the hex value. LAB calculations require a reference white point (illuminant). OKLCH is a perceptually uniform color space and does not require white point configuration.
| Value | Description | Use Case |
|---|---|---|
D50 |
Warm white (~5000K) | Print/graphic arts |
D55 |
Mid-morning daylight (~5500K) | Photography |
D65 |
Standard daylight (~6500K) | Default, web/screen |
D75 |
North sky daylight (~7500K) | Scientific applications |

}Note: Only
nameandhexare required. RGB, CMYK, LAB, and OKLCH values are optional and will be auto-calculated from hex if not provided. If you have official color values (e.g., Solid Coated LAB values), include them to use those instead of calculated values.
List all available color books:
GET /api/laratone/colorbooks| Parameter | Required | Description | Default |

Laratone routes use a laratone middleware alias that does nothing by default. You can replace it with your own middleware to add rate limiting, authentication, or other functionality.
To add rate limiting, define the laratone middleware alias in your application's bootstrap:
// bootstrap/app.php (Laravel 11+)
->withMiddleware(function (Middleware $middleware) {
$middleware->alias([
'laratone' => \Illuminate\Routing\Middleware\ThrottleRequests::class . ':60,1',
]);
})Or in a service provider:
// app/Providers/AppServiceProvider.php
use Illuminate\Routing\Router;
public function boot(Router $router): void
{
$router->aliasMiddleware('laratone', \App\Http\Middleware\YourCustomMiddleware::class);
}You can create a custom middleware class that combines multiple behaviors:
// app/Http/Middleware/LaratoneApiMiddleware.php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Routing\Middleware\ThrottleRequests;
class LaratoneApiMiddleware extends ThrottleRequests
{
public function handle($request, Closure $next, $maxAttempts = 60, $decayMinutes = 1, $prefix = '')
{
// Add custom logic here (authentication, logging, etc.)
return parent::handle($request, $next, $maxAttempts, $decayMinutes, $prefix);
}
}Laratone provides a simple API for managing colors programmatically:
use Daikazu\Laratone\Facades\Laratone;
// Get all color books with colors
$colorBooks = Laratone::colorBooks();
// Get a specific color book by slug
$colorBook = Laratone::colorBookBySlug('color-book-plus-solid-coated');
// Create a new color book
$newColorBook = Laratone::createColorBook('My New Color Book');
// Create with custom slug
$newColorBook = Laratone::createColorBook('My Color Book', 'custom-slug');
// Add a single color to a color book (only hex required)
$color = Laratone::addColorToBook($colorBook, [
'name' => 'New Color',
'hex' => 'FF0000',
]);
// Or with explicit values (these take precedence over calculated values)
$color = Laratone::addColorToBook($colorBook, [
'name' => 'Solid Coated Red',
'hex' => 'FF0000',
'lab' => '53.23,80.11,67.22', // Official Solid Coated LAB value
]);
// Add multiple colors at once
$colors = Laratone::addColorsToBook($colorBook, [
['name' => 'Red', 'hex' => 'FF0000'],
['name' => 'Green', 'hex' => '00FF00'],
['name' => 'Blue', 'hex' => '0000FF'],
]);
// Get all colors from a color book
$colors = Laratone::getColorsFromBook($colorBook);
// Update a color
Laratone::updateColor($color, ['name' => 'Updated Color Name']);
// Delete a color
Laratone::deleteColor($color);
// Find closest matching colors to a target hex
$closest = Laratone::findClosestColors($colorBook, 'FF5500');
// Returns the single closest color by default
// Find multiple closest colors with specific algorithm
$closest = Laratone::findClosestColors(
colorBook: $colorBook,
targetHex: 'FF5500',
limit: 5,
algorithm: 'oklch' // or 'lab' (default)
);
// Each result includes a distance value
foreach ($closest as $color) {
echo "{$color->name}: {$color->distance}";
}
// Clear cache manually
Laratone::clearCache();Color values are automatically cast to associative arrays when accessed. If a value wasn't stored in the database, it will be automatically calculated from the hex value:
use Daikazu\Laratone\Models\Color;
$color = Color::first();
// Access color values as arrays
$color->hex; // 'FF0000' (required, always stored)
$color->rgb; // ['r' => 255, 'g' => 0, 'b' => 0] (stored or calculated)
$color->lab; // ['l' => 53.23, 'a' => 80.11, 'b' => 67.22] (stored or calculated)
$color->cmyk; // ['c' => 0, 'm' => 100, 'y' => 100, 'k' => 0] (stored or calculated)
$color->oklch; // ['l' => 0.6279, 'c' => 0.2577, 'h' => 29.23] (stored or calculated)
// Access the parent color book
$colorBook = $color->colorBook;- Hex is required - All colors must have a hex value
- Other values are optional - RGB, CMYK, LAB, and OKLCH are calculated from hex if not provided
- Stored values take precedence - If you provide explicit values (e.g., official Solid Coated LAB), those are used instead of calculated values
- LAB uses white point config - Calculated LAB values use the
white_pointsetting from your config - OKLCH is perceptually uniform - OKLCH does not require white point configuration and provides consistent perceptual color representation
Laratone automatically caches color book and color data to improve performance. The cache works with any Laravel cache driver, including file, database, Redis, and Memcached.
Cache is automatically cleared when:
- Creating a new color book
- Adding, updating, or deleting colors
To manually clear the cache:
php artisan laratone:clear-cacheOr programmatically:
Laratone::clearCache();See UPGRADE.md for upgrade instructions between major versions.
