Prompting for a Color

Use the Standard Additions scripting addition’s choose color command to ask the user to select a color from a color picker dialog like the one shown in Figure 29-1. The command accepts an optional default color parameter, and produces an RGB color value as its result. Listing 29-1 and Listing 29-2 display a color picker, create a TextEdit document containing some text, and apply the chosen color to the text.
