Colour Illusions
Colour effects the way shapes and figures appear on paper and on a display.
If you look at this picture and randomly move your eyes slowly over it, the effect should be wobble-like.
The colours and pattern create an effect of the image moving.
A solid gray bar is placed onto a gradient background, it seems as though both objects have a gradient colour.
Stare at the black dot in the center, the coloured spots around the picture should disappear.
