I would like to copy colors between elements in the Interface Builder or define them using RGB values. For example, I'd like to copy the background color of a button to another button without duplicating the button.
Alternatively, entering exact RGB codes in Interface Builder would suffice; that way I can make sure my buttons have the exact same color.
Currently I only know how to do this programmatically, but surely there is a way to do it in Interface Builder?
Targets in Xcode.Build Settings on your project's target (your current development name).Product Name under Packaging. Change its value to what you want your new project name to be.
Click on the color slider icon, and then choose "RGB Sliders" from the drop-down list.
You can also use the magnifying-glass as a color picker to pick up an exact color from anywhere on the screen; also see @ken's excellent comment below clarifying how colorspaces work with the magnifying glass.

To copy a custom-defined color between different elements you should save it. To do this, first define the color in the Colors window (e.g. by entering RGB values into field as described in Vladimir's answer). Then simply drag from the top panel of the colors window where your resulting color is shown into one of the small square boxes at the bottom. It will be saved.
