I came across this designer tool called, “Color Oven” by Lima’s Web Design, they also have an OS X version of the application for USD2.99.
The purpose of this application is quite straight forward. You choose a color and the application will generate a set of complimentary colour schemes: monochromatic, complimentary, analogous, or triad, for you.
This application’s features are not unlike many of the web based colour scheme generators, like ColorSchemeDesigner.com. Web site like Colr.org will accept a photo from Flickr or uploaded from the user’s computer, to generate a complimentary colour scheme from it.
