FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

PHP Contrast Tools

Latest Version on Packagist Build Status Quality Score Total Downloads

Provides various utilities for working with color contrast.

The primary purpose is to facilitate easy generation of accessible (minimum 3.0 contrast ratio) hex color pairs. A variation of these tools restricts the generated colors to TailwindCSS's default palette.

I've created a demo page to show how color pairs can be generated by this package.

Installation

You can install the package via composer:

Usage

Import the class.

Check the contrast ratio between 2 colors

Get a random color pair (with the resulting ratio), with minimum 3:1 contrast ratio

Get a random color pair (with the resulting ratio), with minimum specified contrast ratio (but no less than 3:1)

⚠️ Warning For performance reasons, the minimum requested contrast ratio is capped at 4.5, although the generated pairs can go up to the theoretical maximum 21:1 ratio.

⚠️ Caution When chaining with minContrast(), make sure to use getRandom() instead of random().

Get a random accessible sibling for the given color, with minimum specified contrast ratio (but no less than 3:1)

Generate a random TailwindCSS color

Generate a pair of random accessible TailwindCSS colors

Generate a pair of random accessible TailwindCSS colors, with minimum specified contrast ratio (but no less than 3:1)

⚠️ Warning For performance reasons, the minimum requested contrast ratio is capped at 4.5, although the generated pairs can go up to the theoretical maximum 21:1 ratio.

⚠️ Caution When chaining with minContrast(), make sure to use getRandomPair() instead of randomPair().

Merge the default Tailwind colors with a custom palette

You may extend the default Tailwind colors with your own custom palette. Here's an example of how to import a custom palette from a JSON file.
