Colour constancy (IMAGE)
Caption
Both cubes have what appear to be yellow and blue tiles on their top surfaces. However, the ones that look yellow on the left are in fact a grey colour that is identical to the blue tiles on the right. Our model can help explain how objects appear to be the same colour even when the light changes, and why in illusions such grey looks colourful.
