Material Color Picker

I came across this Dribbble shot a little while back and thought it'd be fun to build out for myself. Yes, I am aware there's already a Mac app for it.

I used knockout.js to let the data control the markup, and used currentColor to make the styles a little more elegant. I also added in clipboard.js to make it nice and easy to grab colors.

Suggestions welcome! Especially for how to make the "copy to clipboard" part a little more interesting, as well as any ways to improve/automate text contrast on some of the darker colors.

script.js

var copiedHex = ko.observable();
var clipboard = new Clipboard('#clipboardItem');

clipboard.on('success', function(el) {
    console.clear();
    console.info('Action:', el.action);
    console.info('Text:', el.text);
    console.info('Trigger:', el.trigger);
    el.clearSelection();
    
    copiedHex(el.text);
});
