Thirteen Colors is the easiest way to customize the colors of the Twenty Thirteen theme.
Twenty Thirteen is bold, but if you don’t like its vibrant shades of orange you’ll welcome the ability to transform the theme in a matter of minutes. Just activate Thirteen Colors, head over to the theme customizer, and adjust the default colors to the shades of your liking. Things are kept as simple as possible; colors are grouped into similar usages as in the base theme so you don’t need to worry about contrast if you maintain similar intensities for each color.
Header images are designed to be abstract art for Twenty Thirteen, so Thirteen Colors also integrates with a neat tool that can generate a custom header image in your colors. In a matter of minutes, you can transform WordPress’ default theme for 2013 into a one-of-a-kind masterpiece that’s visually as unique as your content. All of the little details are taken care of, including the editor styles.
By the way, despite the plugin’s name, there are only eight customizable color fields to streamline the process as much as possible. Twenty Thirteen’s original colors are condensed into these eight blocks, but most of the changes are visually indistinguishable.

Sidebar Class or ID – CSS class or ID of the sidebar element that contains widgets.
