About This Design
The Filling-in T-shirt
To do: Fixate your gaze on the centre of one of the figures and stare at it for some time (20-30 seconds) while it cycles (without moving your eyes). After several iterations you’ll start noticing that the empty outlines fill in with ghostly redish or bluish colours! These illusory colours are called “afterimages”. Interestingly, the colours of the afterimages vary, which is puzzling because they come from the same original figure. Moreover, the shape of the outlines determines the filled-in colour, which is complementary to the colour of the same shape in the original figure. What’s happening?
