+      Pick lets you pick colours from anywhere on your screen. Choose the colour you want and Pick remembers it, names it, and shows you a screenshot so you can remember where you got it from.
+
+      Zoom all the way in to pixels to pick just the right one. Show your colours in your choice of format: rgba() or hex, CSS or Gdk or Qt, whichever you prefer. Copy to the clipboard ready for pasting into code or graphics apps.
