Mondrianum

Adobe® kuler is an online community where you can explore and find great color themes.

Lithoglyph’s Mondrianum is a powerful plug-in that enables Mac applications to leverage the resources of the kuler community. Once installed, Mondrianum acts like a built-in, system-wide color picker, available in any Mac application that supports this feature of Mac OS X. Apple’s own iWork™ and iLife® suites, Google Sketchup™, and renowned applications like Coda, CSSEdit, and many more, all work well with Mondrianum.
