Mac only: Colour picker application Mondrianum adds Adobe Kuler colour schemes in a plug-in for OS X—choosing killer colour schemes has never been easier. Once installed, using the application is as simple as opening the colour picker in any application that supports choosing colours with the built-in picker, and then clicking the Mondrianum icon on the right. You can search for colour schemes on the Kuler web site, though accessing the colour scheme data requires an internet connection, so you'll need to be online for it to work—but colour schemes can be saved as Apple colour lists for offline use, making this a great application for anybody trying to find the right colours for their projects.Mondrianum is a free download for Mac, works in most Cocoa apps. If you'd rather create a colour scheme from a picture, check out previously mentioned Colours Pallete Generator, or get colour codes in Firefox with ColorZilla.
