WHEN IS YELLOW YELLOWER THAN YELLOW?
Put a white piece of paper over the left side of the disk and stare at the X for 30 seconds.
After 30 seconds, take away the piece of paper but keep staring at the X.
WHAT'S GOING ON?
Wow—the left side looks much yellower than the right side. The difference in perceived saturation comes from a phenomenon called adaptation. After staring at the same color for a while, the color-sensitive cone cells in your eyes stop responding as strongly as they did at first. This reduced response becomes obvious when you compare it to a "fresh" view of the same color.
Actually, there's nothing special about yellow here. It works with red, blue, green, or any other color—even puce.

Creative Scan-and-Draw Color-Changing Pen Design
Any artist or designer who works with color knows that the best inspiration and perfect coloration can often be found in real-life objects all around us. What if you could take your trusty drawing pen and simply scan any color you want and then turn around and draw with it? This innovative pen design by Jin Sun Park allows you to do just that. Next step? A complete texture selector and replicator?
A color sensor on the top of the pen registers the color of the object you select, which in turn is displayed digitally on the back of the device for verification. Red, green and blue inks are then mixed – much like in a traditional printer – to create your desired color.
Of course, such an invention has its limitations: space for ink and batteries are challenges to be sure, but presumably you would only use this periodically and would also transfer the color data in some cases directly to another electronic advice, thus saving ink. While only in pre-production and sure to be extremely expensive initially one could easily see this become a household gadget and essential tool for every artist and designer for both real-life and web applications.
