<script src="dist/Vibrant.js"></script>

Extracting prominent colors from an image.

var img = document.createElement('img');
img.setAttribute('src', 'examples.png')
img.addEventListener('load', function() {
    var vibrant = new Vibrant(img);
    var swatches = vibrant.swatches()
    for (swatch in swatches)
        if (swatches.hasOwnProperty(swatch) && swatches[swatch])
            console.log(swatch, swatches[swatch].getHex())
});

This will result into:

• Vibrant #7a4426
• Muted #7b9eae
• DarkVibrant #348945
• DarkMuted #141414
• LightVibrant #f3ccb4

Generating a color palette from the image using Vibrant.swatch() method:

// Initialize a new swatch. 
// First argument needs to be an RGB array, second argument must be the swatch' population.
new Swatch()  
// Get swatch color in a RGB array
.getRgb() 
// Get swatch color in hex format (#EE22DD)
.getHex() 
// Get swatch color in a HSL array
.getHsl() 
// Get population (amount of times this color was used in the original image)
.getPopulation()  
// Get a color (in hex) that works best with any 'title' text that is used over this swatch's color
.getTitleTextColor()  
// Get a color (in hex) that works best with any 'body' text that is used over this swatch's color
.getBodyTextColor()
