A simple but invaluable menubar app that instantly samples & encodes any colour on your screen. A quick keyboard shortcut will give you a system wide colour picker that lets you select any pixel on your screen. You can then paste the selected colour directly into your editor in one of several formats including CSS, NSColor, UIColor and CGColor. via http://ios.devtools.me/
Got to know about this new tool Sip from iOS Dev Tools. It’s a color picker that lives in your menu bar and helps you grab any color off the screen. I like it because it is lightweight and it is free. Download Sip Here.
