Why yellow skin?

One of the most iconic aspects of the characters in the show is their yellow skin.

Creator Matt Groening decided to choose the colour rather than more natural tones in order to grab the viewers' attention as they channel surfed.

He said: "An animator came up with the yellow, and as soon as she showed it to me I said, 'This is the answer!' When you're flicking through channels with your remote control, and a flash of yellow goes by, you'll know you're watching 'The Simpsons'."
