– Adds a core-like posts list view <code>Hero Background</code> to show only posts with a custom hero background color 
– Works on elements that have the CSS class <code>hero-colored</code>
Stored as post meta: 
– <code>hero_color_picker_hero_color</code> 
– <code>hero_color_picker_font_color</code>
Frontend output (only when values are set):

 background-color: $background;
 color: $font;
}

 color: $font;
}
</code></pre>
Important template setup: 
– Open your block theme template (for example <code>Single</code>) in the Site Editor.

An add-on for Advanced Custom Fields to allow users to select from a list of color choices. Setting up the field works exactly like setting up a radio button list, the main difference being that the key will also be used to style the element.
This is useful for allowing users to pick from a limited selection of colors, rather than enter an arbitrary hex value or choose from a color picker.
Supports all of the following color formats:
<ul>
<li>hex: #FF0000</li>
<li>rgb: rgb(255,0,0)</li>
<li>rgba: rgba(255,0,0, 1)</li>
<li>hsl: hsl(0,100%,50%)</li>
<li>hsla: hsla(0,100%,50%, 1)</li>
<li>name: red</li>
</ul>
Note: you may also use <code>none</code> to show a transparent swatch with a checkerboard background.
<h3>Compatibility</h3>
This ACF field type is compatible with:
<ul>
<li>ACF 4</li>
<li>ACF 5 (PRO version)</li>
</ul>
