On January 1, 2004, at the stroke of midnight, Mars removed all of the colors of M&M's and made them black-and-white on both their candies and the packaging. It coincided with a commercial parodying "The Wizard of Oz" where Dorothy is home in bed and looks out of the window and sees what the colors of the four M&M's were. The goal was to help the M&M's find their colors in black-and-white packages of M&M's, in this order: brown, orange, red, green, yellow, and blue. After all of the colors have been found, the colored packaging returned, and began carrying the theme "Chocolate is better in color".
