funky-colors

A Wordpress plugin to detect a palette of colors from each image in the media library. Uses Color Extractor and provides Wordpress meta fields and UI.

How

1. Install and activate the plugin, then navigate to Tools > Funky Colors.
2. Press Detect Colors on All Images to detect and save color palettes on each image.
   1. You can view and edit the primary color any time by going to Media, then selecting the image and checking the "Primary Color" field.
3. Use the convenience functions to work with image colors in your template.

Metadata

Funky Colors stores its data in a few meta fields: FIC_color for the primary color, FIC_secondary_color for the manually-set secondary color, and FIC_palette for the image's palette.

It's best to use the get_second_image_color function to find an image's secondary color, since it will fall back to the appropriate value if FIC_secondary_color is not set.

You can use $your_attachment->FIC_color to find the main hex color of an image and $your_attachment->FIC_palette[1] to find the secondary hex color. The FIC_palette works like a zero-indexed array - substitute 1 with any number between 2 and 4 to try to find the third to fifth most common colors.

Convenience Functions

• get_primary_image_color( $attachment_id ) Returns the hex value of an image's primary color, if it has one. Returns an empty string otherwise.
• get_second_image_color( $attachment_id ) Returns the hex value of an image's secondary color, if it has one. Uses the manually-set value first, then falls back to the secondary color from the palette. Returns an empty string if none found.
