### Generating Color Triads

[](#generating-color-triads)

To get a color triad based on a base color:

```
require 'vendor/autoload.php';

use OwenJones\ColorKit\ColorKit;

$baseColor = '#3498db';
$triad = ColorKit::getColorTriad($baseColor);

print_r($triad);
// ['#3498db', '#db3434', '#34db34']
```

The first 2 colors are guaranteed to be accessible. The third is not.

### Checking Color Contrast

[](#checking-color-contrast)

To check if the contrast between two colors is accessible (contrast ratio of at least 4.5):

```
use OwenJones\ColorKit\ColorKit;

$color1 = '#3498db';
$color2 = '#ffffff';

$isAccessible = ColorKit::isContrastAccessible($color1, $color2);

echo $isAccessible ? 'Accessible' : 'Not Accessible';
```
