The King’s Palace

A good demonstration of the color of light, courtesy of Carlsbad Caverns in New Mexico:

The King's Palace

This is one of the “marquis” attractions at Carlsbad Caverns, but really doesn’t look this colorful in person (Journey to the Center of the Earth not withstanding).  But it’s lit by spotlights of slightly different color temperature — so if you grab a picture on your visit, and attempt to pick some feature for your white balance, you’ll wind up with this slightly gaudy view in your photo.
