These rectangles are perfectly parallel to each other. Really! |

I didn't either. I even took the time to erase everything except the two squares to come to the conclusion that it was true. |

Consider that in reality, whatever color your shirt is has very different images, in terms of the wavelength of light, depending on whether you're outside in sunlight or inside in artificial light, or in relative darkness. However, your brain is used to seeing them as 'the same thing' and attributes the same color to it regardless (color constancy). The square A and B trick plays on that ability. |
