On the contrary... thats simple biology and physics.
The wrong colored pic you stare at is tiring your optical sensor nerve cells (retical cones) in the eyes for one color. Then later, looking at the grey image, the cones simply "ignore" the color they are tired of and thus it gets "subtracted" from the grey light - pic looks colored.
(You can have the same effect if you stare at a red colored spot for a while, then, directly afterwards look at the white wall.... makes the red thing you looked at appear on the wall in green color.)
