A WordPress plugin to automatically save the dominant color and a color palette for an attachment image into post_meta.
The dominant color and color 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 colors that feature prominently in the image.

Add a colour picker to the attachment edit screen to override the dominant color with a custom pick.
The WordPress media gallery will now let you pick a dominant color override which will be returned in place of dominant_color_hex/rgb when set.
It’ll also let you generate a palette for legacy images uploaded before you installed the plugin.
