simultaneous contrast
of tone
the same grey, shown as a central square, gives
the illusion of being lighter set against a dark tone
and darker when set against a light tone
Next
simultaneous contrast
the same effect occurs when the same grey
is set against colours of different value
Next
look at the central spot
after a few seconds the same grey has the illusionof appearing different in colour - taking on a complementary hue of its background colour
Next
look at the central spot
after a few seconds the same yellow has the illusionof appearing different in colour - it appears more intense set against a contrasting hue

successive contrast
look at the central spot and try to remain fixed on it until the screen changes
Next
successive contrast
the complementary colour appears as an afterillusion as your eyes adjusted to the loss of colour
