Would you look at this! I can't even tell you how many times I see something out in the world and think, if only I could have that color. This is the blurb from Incrediblethings.com:
Nature is treasure trove of endless color. Now you can capture those glorious hues with a device called the Color Picker, which allows you to take any color, from any source, at any time. The color is detected and scanned by the color sensor, and the RGB cartridge inside the pen mixes the required inks to create the target color. Want a red as brilliant as a Macintosh apple, green as fresh as spring's first blossoms? With the Color Picker, they're at your fingertips and on paper in seconds.
