Adobe has released a colour selection tool for Macs which employs the Kuler technology the company has been developing in its labs.

The free Dashboard Widget helps users quickly create harmonious colour themes based on predefined colour formulas. Users can also mix their own themes using an interactive color wheel.

The Widget calls on Adobe's web-hosted application that was developed to complement Adobe CS 2. The technology uses Flash and ActionScript to allow users to search for, create and share colour themes.

The Widget flicks through the most recent themes published on the Kuler website, and also lets users search by specific tags, such as summer or winter.

Kuler community programme manager Sami Iwata, quoted on John Nack's blog, says that the widget: "Displays RSS feeds of colour themes from kuler. Browse the newest, highest rated, and most popular themes; search for themes on the kuler site by tag, title, or creator ID."

The software also lets designers copy the colour values to their Clipboard so they may apply them within their design projects.

The hosted version also allows users to download Kuler colour themes as an Adobe Swatch Exchange (.ASE) file for use in Creative Suite 2 applications.

The Widget is available for download (200k) here.
