<p>Image Color Palette provides a simple utility to generate a color palette based on the dominant colors of an image. It also creates color schemes based on the image colors.</p>
<p>The colors can be copied to the clipboard and pasted in a color picker. When a registered block is selected the plugin permits applying the color to certain block attributes like text or background color.</p>
<h3>Color schemes</h3>
<p>Available schemes include:</p>
<ul>
<li>Analogous</li>
<li>Monochromatic</li>
<li>Triad</li>
<li>Complementary</li>
<li>Lighter</li>
<li>Brighter</li>
<li>Darker</li>
<li>Desaturated</li>
<li>Saturated</li>
</ul>
<h3>Usage</h3>
<p>Go to any post editor where the new Gutenberg editor is enabled.<br />
Inside the Post editor on the right side of the top Toolbar the plugin icon/button should appear (if not, please read the FAQ below).<br />
Click the icon/button to open the plugin sidebar.<br />
Click the main button and the Media Library will open. Select an image and click the Select button.<br />
A color palette will be created based on the colors of the image.<br />
Click on any of the colors and a menu will appear.<br />
The color can be copied to the clipboard (in HEX format) and pasted in the color picker of any block.<br />
For supported blocks, the menu will display extra options to apply the color directly to the Block attributes.</p>

WP Term Colors

I needed to save colors for terms, and found that @jjj had already done the work. Accessing the saved colors is pretty straightforward using the new (WP 4.4 or newer) built-in utility function:
$color = get_term_meta( $term_id, 'color', true );
The terms are saved in hex format (#eeee22) so are ready to use once retrieved.
Thanks @jjj.



Works well with WP's new termmeta table
