Hugh is a social color experiment for WordPress. Add the Hugh widget to any sidebar and visitors to your site can pick a color — background, text, the whole page — and broadcast it to everyone else viewing the site at the same time.
How it works:
<ol>
<li>A visitor opens the color picker in the Hugh widget, chooses a hex color, and optionally leaves a short note.</li>
<li>Hugh pushes that color via the REST API and stores it (up to 100 recent entries).</li>
<li>The page background and text color transition smoothly to the new color for all active visitors.</li>
<li>A row of color swatches shows the history of recent choices — click any swatch to jump back to that color.</li>
</ol>
It’s part toy, part social experiment: can your visitors agree on a color, or will it descend into a color battle?
Technical details:
<ul>
<li>Colors are stored via the WP object cache when an external cache (Memcached, Redis) is available, making it fast and ephemeral. Without an external cache it falls back to a WP option for persistence.</li>
<li>Color history is capped at 100 entries, sorted by timestamp.</li>
<li>REST endpoints at <code>hugh/v1/colors</code> (GET) and <code>hugh/v1/colors/add</code> (POST) are public and unauthenticated by design — this is intentional for the live-sharing mechanic.</li>
<li>The <code>hugh_css</code> filter lets themes register custom CSS overrides. Twenty Seventeen support is built in; other themes can hook in via <code>add_filter( 'hugh_css', ... )</code>.</li>
<li>Colors are rendered as smooth CSS transitions so the page doesn’t flash when a new color arrives.</li>
</ul>
Note: Hugh works best on sites with an external object cache. Without one, colors are persisted to the database and shared state may lag under concurrent visitors.

Hugh is your personal color consultant. However, Hugh also easily gives in to peer pressure.

Finally a cool way to display color palettes on your site. This tiny little plugin gives you a cool way to display color palette on your pages.
Example of what it looks like: 
http://halgatewood.com/palettes/
Use the shortcode to and pass in a list of colors:
<pre><code>[awe_palette colors="434858,5886c5,#f2674a,c6006d"]
</code></pre>
Or you can call it directly with PHP in your theme:
<pre><code><?php awesome_color_palettes( array('#cccccc', 'efefef', '666') ); ?>
</code></pre>
You can include the # or not, it doesn’t care what you do.
Wait, there’s more. Create an <code>awesome-color-palette.php</code> file and put it in your theme folder and you can custom palettes for whatever you need.
It can handle 10 colors out of the box. To add more, simply create some CSS like below and add it to your style.css file in your theme.
<pre><code>.awe-color-palette.count-20 .color { width: 5%; }
</code></pre>
