Installation

The dominant colour and colour palette is automatically saved on upload and edit to post meta.

You need to then use get_post_meta to retrieve the “dominant_color_hex” or “dominant_color_rgb” meta key. hex returns a string, including the #, rgb returns an array with key 0 as red, 1 as green, and 2 as blue.

Alternatively, you can use the meta keys “color_palette_rgb” and “color_palette_hex” to get an array of 8 colours that feature prominently in the image.

Pulls out both the dominant color and a nice color palette. Far more efficient to do this calculation once on upload rather than via PHP or JavaScript when rendering the page. Perfect!

I had to search the post_meta table to find out how the 'dominant_override' meta_key - it would have been useful to find that in the release notes. A bulk calculate feature would be excellent - along with a way of colour picking the override from the posts screen in the WP Dashboard. Otherwise, perfect for what I need 🙂
