Sameer Borate has posted a simple method for creating a color palette from a given image using just PHP and GD.

In the previous post we saw how we can generate a screenshot from a url. In this post we will see how we can create a color palette of the screenshot (or any other image for that matter) using PHP and GD. This can be useful if you need to quickly get the color scheme of a website or a image. Below are a few example images and their palettes generated using the program.

With the help of his code it's as easy as a call on a GetMostCommonColors object (get_color) to return the hex codes for the values found most. Also included in the post is a sample snippet showing how to pull the details from the file and output it in a grid similar to this.

In the latest entry to his blog, Mikko Koppanen shows how to take the power of Imagick and harness it to check and see what sorts of colors an image contains:

The code in the example reduces the image colors to 10, then discards all but one pixel of every color and then creates the palettes out of those colors. This might not be the most accurate way to do this, but at least it's fast.

His code makes three different "palettes" from the image - average, dark and light - and outputs them as a range of colored boxes for each all of the three palettes. Examples of the output are also included in the post.

On BarelyFitz Designs, there's a handy tutorial that's been posted to help developers out there combine the powers of PHP and CSS to form a sort of color management system for their site.

They follow the steps to making a CSS file with PHP - generate the header and output the CSS - as well as examples of its usage. They create a range of colors based around a central one, five levels in either direction. The file they've created to accomplish this is also available for download.
