Pick (ColourPicker) – a small color picker allows you to get and save the color of any pixel on the screen.Using a Pick is very simple, you need to launch the “magnifier” button (the button at the top left of the window), bring it to the desired portion on the monitor screen and click on the desired color. The color is automatically added to the list (in specified format), Lens supports zoom in/out (mouse wheel).
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.
