Discussion questions

Talk about it

Your eyes send signals about light to your brain, but the brain interprets those signals using clues like nearby colors and shadows. An optical illusion works by fooling that guesswork, so you can 'see' a color that isn't really there.

  1. What do your eyes send to your brain when you look at something?
  2. How can two identical colors look different to us?
  3. Why does an illusion prove your brain 'decides' what you see?
