Color Palette Generator

Generate color palettes for your WordPress images, append them to your images inside your content and make searching images by color available to your visitors.

Description

This plugin is ideal for blog owners who like to do something more with their images, or for webshop owners who like to filter products by color. When inserting images you have the option to show the palette for that image. You can also use the following shortcode to show a specific image with palette: [colorpalette attachment="56" dominant="false" colors="10" size="large" random="true"]

Features

  • Generate color palettes per image
  • Bulk-generate color palettes for all images
  • Allows configuration of number of unique colors per image
  • Allows configuration of auto appending palettes on attachment pages
  • See stats of generated palettes
  • Filter attachments by color
  • Add color search widget to your sidebar
  • Use a shortcode to show an image with a palette in your content.

Developers

If you don't like the way the plugin outputs the palettes, or you want to create custom color queries yourself, use the wordpress taxonomy functions. There are 2 new taxonomies added when the plugin is activated: cpg_dominant_color and cpg_palette. The first one holds one color per image, the dominant color (this color is used to link the image to one of the main colors used in the color search functions). The second one holds the palette, and the number of colors is based on what the site owner has entered (default = 10).

If you want to create your own search template, add a templates folder in your theme and add a search.php file in there. If that file is found it will be used to show the searchresults. Else the template from the plugin will be used.
