An OS X app for creating and managing beautiful colour schemes. Spectrum uses colour theory and harmony rules to make it easy to create aesthetically pleasing colour schemes by suggesting complementing shades and tints that go well with your existing swatches. It can also automatically generate colour schemes from images and lets you capture colours from your screen using the built-in colour picker. Unfortunately it cannot export to UIColor or NSColor but it does support CSS, PNG, Photoshop and Illustrator. There is also an iOS version so you can create colour schemes on the go!
